Development Of Electrochemical Sensors And Non-Covalent Monolayer Modification Of Graphene
… reproducibility is a necessity for calibration-free electrochemical sensors. Previously, our group introduced cobalt(II)/cobalt(III) redox buffers as an inner reference to improve the electrode-to-electrode reproducibility of solid-contact ion-selective electrodes (SC-ISEs), making …

Characterizing the structure of transmission matrix in lower dimensions
… for weakly deformed fibers. We will look into calibration-free, real-time methods to determine the TM of a fiber with flexibility in conformation. The proposed method is to find a lower dimensional representation of the TM which reduces the number of unknown parameters of the TMs for different …

Diode Laser Spectroscopy for Measurements of Gas Parameters in Harsh Environments
… modulation amplitude. Like previously proposed calibration-free approaches, this new method also yields absolute gas absorption line shape or absorbance function. Residual Amplitude Modulation (RAM) contributions present in the first and second harmonic signals of WMS are recovered by exploiting …

Investigation of the effects of colloidal suspension properties on spatially resolved diffuse reflectance
… The developed methodology does not require a calibration model and was used to investigate three main objectives. Firstly, the sensitivity of the simulated SAR-DRM to the mode radius, distribution width and concentration of solids variations is explored.;An inversion algorithm for the measured …

Influence of motion profile on estimating anatomical elbow joint axes using inertial measurement units
… typically rely on precise alignment, static calibration poses, or dynamic calibration motions. Muller et al. recently proposed a method for online calibration of the human elbow anatomical joint axes via decomposition of angular velocity measurements. This thesis evaluated this …

Supercontinuum radiation for ultra-high sensitivity liquid-phase sensing
… dye species dissolved in water. SC-CEAS is not calibration-free and for this purpose a second technique, a time-resolved variant called broadband cavity ring-down spectroscopy (BB-CRDS), was successfully developed. Use of a novel single-photon avalanche diode (SPAD) array enabled the …
