Setting the Stage for Deception. Perspective Distortion in World War I Camouflage

open access: yesAisthesis, 2016
During World War I, in response to substantial advancements in wartime surveillance, it became a common practice to rely on “vision specialists” to devise effective methods of fooling the enemy (tromper l’ennemi).

Jakob Leupold’s Imaginary Automatic Anamorphic Devices of 1713 [PDF]

open access: yes, 2016
In 1713 the scientific instrument-maker Jakob Leupold published designs for three machines were the first attempt to design machinery with internal moving parts that replaced human agency in creating original images.

A Hybrid Data Assimilation Approach Integrating Kalman With Deep Learning‐Based Updates for Nonlinear and Non‐Gaussian Groundwater Systems

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract In hydrological research, data assimilation (DA) is a powerful tool for integrating observational data with numerical models, significantly enhancing predictive accuracy. However, nonlinear groundwater systems often exhibit high‐dimensional and non‐Gaussian characteristics in observations, parameters, and state variables, posing substantial ...

Triangulation of research methods in social phenomena research: anamorphic objection [PDF]

open access: yesZbornik radova (Univerzitet u Kragujevcu. Pedagoški fakultet u Užicu), 2018
Starting from the problems of bias and validation in combining different research methods and methodologies, the paper discusses the advantages and shortcomings of triangulation. The triangulation concept which involves the use of more than one method to

Remote Sensing Data Assimilation With a Chained Hydrologic‐Hydraulic Model for Flood Forecasting

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Effective flood risk management requires reliable forecasts with extended lead times to enable the implementation of cost‐effective and timely measures. In this study, we present a chained hydrologic‐hydraulic modeling framework designed for effective near‐real‐time flood forecasting. The system integrates runoff predictions from a large‐scale

Ensemble Kalman filter in latent space using a variational autoencoder pair

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 152, Issue 775, January 2026 Part B.
The use of the ensemble Kalman filter (EnKF) in strongly nonlinear or constrained atmospheric, oceanographic, or sea‐ice models can be challenging. Applying the EnKF in the latent space of a variational autoencoder (VAE) ensures that the ensemble members satisfy the balances and constraints present in the model.

Can ensemble‐based parameter estimation aid parameterization design?

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 151, Issue 772, October 2025 Part A.
Parameterization schemes rely on uncertain empirical parameters, the values of which can be estimated objectively and iteratively with ensemble data assimilation methods. Since all sources of forecast error in the background ensemble project onto parameter adjustments, the estimated parameters may converge to implausible values or not converge at all ...

Anamorphosis: optical games with perspective's playful parent [PDF]

open access: yes, 2017
We explore conical anamorphosis in several variations and discuss its various constructions, both physical and diagrammatic. While exploring its playful aspect as a form of optical illusion, we argue against the prevalent perception of anamorphosis as a ...
