Stochastic Analysis of England Grain Prices 1750-1850
Moxnes, John Fredrik; Hausken, Kjell (2012)We study the prices of grain in England 1750-1850, with special attention to the Tamboro volcano eruption time period 1815-1820. Two different types of time series are constructed and compared with the historical data. ... -
Stochastic Theories and Deterministic Differential Equations
Moxnes, John Fredrik; Hausken, Kjell (2010-05)We discuss the concept of “hydrodynamic” stochastic theory, which is not based on the traditional Markovian concept. A Wigner function developed for friction is used for the study of operators in quantum physics, and for ... -
Strain rate dependency and fragmentation pattern of expanding warheads
Moxnes, John Fredrik; Prytz, Anne K.; Frøyland, Øyvind; Skriudalen, Stian; Børve, Steinar; Ødegårdstuen, Gard (2014-12-22)For the characterization of the behaviors of a metal material in events like expanding warheads, it is necessary to know its strength and ductility at high strain rates, around 104 e105 /s. The flyer plate impact testing ... -
A Study of the Detonation Properties, Propellant Impulses, Impact Sensitivities and Synthesis of Nitrated ANTA and NTO Derivatives
Jensen, Tomas Lunde; Moxnes, John Fredrik; Kjønstad, Eirik Fadum; Unneberg, Erik (2016)Nitrated derivatives of 5-amino-3-nitro-1,2,4-triazole (ANTA) and 3-nitro-1,2,4-triazol-5-one (NTO) were theoretically characterized with respect to their performance as high explosives and rocket propellants. The detonation ... -
Study of thermal instability of HMX crystalline polymorphs with and without molecular vacancies using reactive force field molecular dynamics
Moxnes, John Fredrik; Jensen, Tomas Lunde; Unneberg, Erik (2016)The sensitivity of energetic materials can be identified by heat, friction, impact, shock, electrostatic charge, etc. A complexity of various factors may influence the sensitivity and among them are the crystal structure ... -
Studying the time trend of Methicillinresistant Staphylococcus aureus (MRSA) in Norway by use of non-stationary γ-Poisson distributions
Moxnes, John Fredrik; Moen, Aina Elisabeth Fossum; Leegaard, Truls Michael (2015)Objectives Study the time development of methicillin-resistant Staphylococcus aureus (MRSA) and forecast future behaviour. The major question: Is the number of MRSA isolates in Norway increasing and will it continue to ... -
Synthesis and characterization of Al@MOF materials
Langseth, Eirin; Swang, Ole; Arstad, Bjørnar; Lind, Anna Maria; Cavka, Jasmina Hafizovic; Jensen, Tomas Lunde; Kristensen, Tor Erik; Moxnes, John Fredrik; Unneberg, Erik; Heyn, Richard H. (2019)The potential impregnation of Al(0) nanoparticles in the pores of three different metal-organic frameworks (MOFs), MIL-53-Al, HKUST-1, and UiO-67, was investigated through the suspension of the MOFs in AlH3•NMe2Et (1), ... -
Using the Power Balance Model to Simulate Cross-Country Skiing on Varying Terrain
Moxnes, John Fredrik; Sandbakk, Øyvind; Hausken, Kjell (2014)The current study adapts the power balance model to simulate cross-country skiing on varying terrain. We assumed that the skier’s locomotive power at a self-chosen pace is a function of speed, which is impacted by friction, ...
