Simulation in statistics

Proceedings of the 2011 Winter Simulation Conference (WSC), 2011
Simulation has become a standard tool in statistics because it may be the only tool available for analysing some classes of probabilistic models. We review in this paper simulation tools that have been specifically derived to address statistical challenges and, in particular, recent advances in the areas of adaptive Markov chain Monte Carlo (MCMC ...

A Carbonaceous Chondrite Based Simulant of Phobos

, 2016
In support of an ESA-funded concept study considering a sample return mission, a simulant of the Martian moon Phobos was needed. There are no samples of the Phobos regolith, therefore none of the four characteristics normally used to design a simulant ...

Lunar Polar Environmental Testing: Regolith Simulant Conditioning

, 2014
As ISRU system development approaches flight fidelity, there is a need to test hardware in relevant environments. Extensive laboratory and field testing have involved relevant soil (lunar regolith simulants), but the current design iterations necessitate

The Research on Lunar Soil Simulant Production System

, 2011
Because the lunar soil is rarely, lunar soil simulant plays an important part in lunar exploration, development and utilization of lunar resources, to establish a lunar base research work. This paper presents a lunar soil simulant production system which

Analytical data on three Martian simulantsResearch Data Unipd

Data in Brief
The preparation of planetary missions as well as the analysis of their data require a wide use of planetary simulants. They are very important for both testing mission operations and payloads, and for interpreting remote sensing data.

Differential thermal analysis of lunar soil simulant

, 1991
Differential thermal analysis of a lunar soil simulant, 'Minnesota Lunar Simulant-1' (MLS-1) was performed. The MLS-1 was tested in as-received form (in glass form) and with another silica.

Tribocharging Lunar Simulant In Vacuum For Electrostatic Beneficiation

, 2007
Electrostatic beneficiation of lunar regolith has potential application for separating minerals for material processing on the moon. This paper describes the use of tribocharging lunar simulant prior to mineral grain separation.

A Comparison of Different Protocols for the Extraction of Microbial DNA Inhabiting Synthetic Mars Simulant Soil

Microorganisms
Compared with typical Earth soil, Martian soil and Mars simulant soils have distinct properties, including pH > 8.0 and high contents of silicates, iron-rich minerals, sulfates, and metal oxides.

Anm Model Approach for Lunar Soil Simulant Properties Study

, 2015
In this paper, the upgraded Anm model, which places multiple particles into a 3D unit cell, was used to study the microstructural properties of lunar soil simulant.
