A is a continuous-time, real-valued stochastic process which has independent and Levy jump process stationary increments, with no Brownian component. We study some of the fundamental properties of Levy jump processes and develop inventory models for them. Of particular interest to us is the gamma-distributed Levy process, in which the demand that occurs in a fixed period of time has a gamma dis...

Control of reasoning isa major issue in scaling up problem solvers that use declarative representations, since inference isslowed own significantly as the size of the knowledge base (KB) is increased. A key factor for the slow down is the search of the inference engine through parts of the KB that are irrelevant to the query at hand. The ability of a system to ignore irrelevant information is t...

Galilean Electromagnetism was discovered thirty years ago by Levy-Leblond & Le Bellac. However, these authors only explored the consequences for the fields and not for the potentials. Following De Montigny & al., we show that the Coulomb gauge condition is the magnetic limit of the Lorenz gauge condition whereas the Lorenz gauge condition applies in the electric limit of Lévy-Leblond & Le Bella...

Levy et al. (2002) describe portions of their analysis of the public health impacts of emissions from nine power plants in Illinois. This and similar analyses (Levy and Spengler, 2002; Freeman, 2001; Abt, 2000) use dataintensive models of air quality and health risks to estimate the number of deaths caused by increases in ambient particulate matter (PM) concentrations due to emissions from spec...

Abstract This paper is a first attempt to provide quantitative evaluation of consumer well-being resulting from the UK Soft Drinks Industry Levy introduced in April 2018. Using model setup that encompasses both normal case and Giffen for sugary drinks consumption, computational exercise performed quantify welfare social loss variety household incomes. The demonstrates introduction soft levy res...

Levy walk (LW) process has been used as a simple model for describing anomalous diffusion in which the mean squared displacement of walker grows non-linearly with time contrast to diffusive motion described by random walks or Brownian motion. In this paper we study extension LW one dimension introducing correlation among velocities different (flight) steps. Such is absent model. The correlation...

This instrument test, classical assumption f test R² test. results are as follows: (i) lots...

We report that human walk patterns closely follow Levy walk patterns commonly observed in animals such as monkeys, birds and jackals. Our study is based on about one thousand hours of GPS traces involving 44 volunteers in various outdoor settings including two different college campuses, a metropolitan area, a theme park and a state fair. Important implications of this finding include that many...

What are the costs of litigation? David M. Trubek the author of The Costs of Ordinary Litigation breaks down litigation into "events" to answer this question. Through a study that randomly sampled civil cases from federal district and state courts, data has been complied and broken down into categories or stated differently into "events of litigation." [1] The study's data focuses on an attorne...
