Finding by Counting: A Probabilistic Packet Count Model for Indoor Localization in BLE Environments

open access: yes, 2017
We propose a probabilistic packet reception model for Bluetooth Low Energy (BLE) packets in indoor spaces and we validate the model by using it for indoor localization.

Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

open access: yesAdvanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

POSTER: Privacy-preserving Indoor Localization

open access: yes, 2014
Upcoming WiFi-based localization systems for indoor environments face a conflict of privacy interests: Server-side localization violates location privacy of the users, while localization on the user's device forces the localization provider to disclose ...

Experimental evaluation of UWB indoor positioning for indoor track cycling [PDF]

open access: yes, 2019
Accurate radio frequency (RF)-based indoor localization systems are more and more applied during sports. The most accurate RF-based localization systems use ultra-wideband (UWB) technology; this is why this technology is the most prevalent.

On Indoor Localization and Indoor Mapping [PDF]

open access: yes, 2023
This thesis proposes novel methods for the generation of indoor maps and localization. For enabling these approaches, significant improvements were introduced in state-of-the-art methods for the identification of the user transition between out and indoor areas, vertical and horizontal localization, and radio-map generation, while generating 3D models ...

Selective Benzene Capture by Metal‐Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) hold significant potential for capturing benzene from air emissions and hydrocarbon mixtures in liquid phases. This capability stems from their precisely engineered structures, versatile chemistries, and diverse binding interactions.
