Qpack, a general tool for instrument simulation and retrieval work [PDF]
Journal of Quantitative Spectroscopy and Radiative Transfer, 2005 Remote sensing requires a complete observation system, consisting of the instrument, a forward model and a retrieval environment. This paper presents a software tool to complement atmospheric sensors, with focus on passive instruments operating in the mm and sub-mm wavelength regions. The tool is of general character and offers a complete, flexible and

Navigating Separated Instrument Retrieval: A Case Report. [PDF]
Cureus, 2023 Instrument separation during endodontic therapy is a complication occurring in 2% to 6% of cases. Focusing on the Masserann technique, the study presents a success rate of 55% in retrieving separated instruments. The technique's effectiveness is demonstrated through a case involving retrieving an instrument from the mandibular first premolar.

Operational and scientific limb retrieval for the SCIAMACHY instrument [PDF]
, 2009 In this poster we present a comparison between limb retrieval results obtained by using the operational and a scientific processor for the SCIAMACHY instrument. The scientific processor uses as forward model, a Picard iteration model, and as inversion model, direct and iterative regularization methods.
