Random Numbers and Gaming [PDF]

open access: yes, 2017
In Counter Strike: Global Offensive spray pattern control becomes a muscle memory to a player after long periods of playing. It’s a design choice that makes the gunplay between players more about instant crosshair placement with the faster player usually

Random time changes of Feller processes

open access: yes, 2017
We show that the SDE $dX_t = (X_{t-}) \, dL_t$, $X_0 \sim $ driven by a one-dimensional symnmetric $ $-stable L vy process $(L_t)_{t \geq 0}$, $ \in (0,2]$, has a unique weak solution for any continuous function $ : \mathbb{R} \to (0,\infty)$ which grows at most linearly. Our approach relies on random time changes of Feller processes.

Countably many simultaneous random changes of time scales

open access: yesStochastic Processes and their Applications, 1984
In this work the author extends previous work by himself [Adv. Math. 12, 32-57 (1974; Zbl 0379.60096)] on the finite dimensional-time changes case to the countably-infinite-dimensional time changes problem. For that he constructs the relevant processes, \(\sigma\)-algebras and defines correspondingly the infinitely many components time changes. He then

A Pretreatment Method for the Velocity of DVL Based on the Motion Constraint for the Integrated SINS/DVL

open access: yesApplied Sciences, 2016
It is difficult for autonomous underwater vehicles (AUVs) to obtain accurate aided position information in many locations because of underwater conditions.

Modifying Colourings Between Time-Steps to Tackle Changes in Dynamic Random Graphs [PDF]

open access: yes, 2016
Many real world operational research problems can be formulated as graph colouring problems. Algorithms for this problem usually operate under the assumption that the size and constraints of a problem are fixed, allowing us to model the problem using a static graph.

Pairwise Interaction on Random Graphs [PDF]

open access: yes
We analyze dynamic local interaction in population games where the local interaction structure (modeled as a graph) can change over time: A stochastic process generates a random sequence of graphs. This contrasts with models where the initial interaction

On adaptive refinements in discrete probabilistic fracture models

open access: yesFracture and Structural Integrity, 2016
The possibility to adaptively change discretization density is a well acknowledged and used feature of many continuum models. It is employed to save computational time and increase solution accuracy.

A Random Time Change Relating Semi-Markov and Markov Processes

open access: yesThe Annals of Mathematical Statistics, 1968
We investigate the question of when a semi-Markov process is transformed by a random time change into a Markov process.

Predictors of change in CD4 cell count over time for HIV/AIDS patients on ART follow-up in northern Ethiopia: a retrospective longitudinal study

open access: yesBMC Immunology
Background HIV has an effect on lowering CD4 cell count, which lowers the ability to resist contamination. For patients on ART in areas with limited resources, the CD4 cell count assessment is crucial for determining treatment responses and therapeutic ...

A construction of a $\beta$-coalescent via the pruning of Binary Trees

open access: yes, 2012
Considering a random binary tree with $n$ labelled leaves, we use a pruning procedure on this tree in order to construct a $\beta(3/2,1/2)$-coalescent process. We also use the continuous analogue of this construction, i.e. a pruning procedure on Aldous's
