title: Design of a Hydrogen Fuel Cell Powered Long-Endurance Drone for Wildfire Detection
title: Links to all related documents:

description: &lt;b&gt;Purpose&lt;/b&gt; – In this bachelor thesis, a drone is developed that will be used for early wildfire detection. The drone should also be able to be used by authorities to detect oil spills or to provide live images in the event of disasters and large-scale emergency operations. In order to keep noise and environmental pollution in the area of operation as low as possible, the drone is to be powered by hydrogen with fuel cells. ---
Methodology – The calculations are based on scripts by Professor Scholz on aircraft design and Professor Sadraey on the design of unmanned aerial systems. Microsoft Excel was used to calculate the matching charts. The requirements for such a drone have been discussed with potential customers and authorities, as well as aid organizations that are already using drones. ---
&lt;b&gt;Findings&lt;/b&gt; – The results from the draft do not meet all the previously established requirements. The flight time and also the range fall far short of expectations. During the design, many assumptions had to be made that have not yet been confirmed by empirical values. ---
&lt;b&gt;Practical implications&lt;/b&gt; – The results achieved in the design make it clear that the use of hydrogen poses many challenges. It turns out that hydrogen propulsion is currently associated with high weight and short ranges and that empirical values urgently need to be gained in order to optimize the design of hydrogen-powered aircraft. ---
&lt;b&gt;Social implications&lt;/b&gt; – The draft shows a possibility that allows the use of environmentally friendly technology to protect the population. In addition, the challenges faced for the use of this technology are shown. ---
&lt;b&gt;Originality&lt;/b&gt; – This is the first time that a design has been developed with this detail using the methods for conventional transport aircraft in conjunction with the methods for unmanned aerial vehicles for a hydrogen-powered drone. The challenges and limitations of a hydrogen-powered aircraft are demonstrated for the first time.

title: pAcOrn–BISS/Al3+ hydrogels based on derivatives of natural amino acids for sensing activity

description: This dataset presents a series of multifunctional hydrogels developed using aluminum ion (Al3+) coordination chemistry to enhance self-healing, mechanical strength, and sensing performance. These hydrogels are built from poly(N-δ-acryloyl ornithine) (pAcOrn) monomers and crosslinked with N,N′-bisacryloylcystine (BISS), alongside varying concentrations of Al3+ ions. The aluminum ions interact dynamically with amino acid side chains, introducing reversible coordination bonds that boost the hydrogel's ability to self-repair and maintain structural integrity under repeated stress.The dataset includes performance metrics for multiple formulations, with BISS concentrations set at 0.4, 0.7, and 1 mol%, and Al3+ contents ranging from 0 to 1.5 wt%. Notably, the hydrogel with 0.7 mol% BISS and 1 wt% Al3+ (pAcOrn–0.7%BISS/1%Al3+) showed outstanding properties: over 900% elongation, breaking strength near 9.5 kPa, and the ability to recover 57.4% of its stress within just 2 minutes after damage. These characteristics were further enhanced using laser irradiation to activate and tune the Al3+–amino acid interactions.In addition to mechanical resilience, this hydrogel demonstrated promising electrical responsiveness. It showed quick and consistent signal behavior during bending, with response and recovery times of 1200 ms and 1300 ms, respectively. The electrical output correlated linearly with applied strain (R2 = 0.992), and the presence of Al3+ significantly improved the gauge factor, making this system a strong candidate for applications in motion tracking and flexible strain sensors.Altogether, this dataset offers helpful information regarding the role of aluminum ions in designing tunable, self-healing, and responsive hydrogels. It includes mechanical testing data, recovery performance, strain sensing output, and formulation parameters for each variant.

title: Modeling of Dynamics of Nonideal Mixer at Oscillation and Aperiodic Damped Mode

description: If the engine power (torque a) is insufficient for the rotary motion of the crank, then the crank will perform a damped oscillation process. The crank, under the action of torque a, initially rotates upwards by some angle and then falls downwards, before reaching the neutral equilibrium position under the action of torque it rises again, etc., until the oscillations are completely damped out.

title: Dataset to support the EARA Farmer-led Research on Europe's Full Productivity

description: The survey data was collected between June 2024 and March 2025 from Pioneering farmers across Europe and from Eurostat. We share the structured data as it was collected from the farmers and Eurostat and as it was used for data analysis. Also, included is the codebook which explain each variable names and unit. Additionally, we share our survey used for data collection.

 

Version 5

In version 4 we found a formula issue with calculating the gross margin which is now corrected in version 5. Also we have introduced the data from two farmers, one from Finland and one from Spain. We also corrected an issue with the data in the EurostatData sheet where some country connections were off.

When we introduced the new farmer from Spain we noticed that the feed imports data needed a different approach. Initially, feed origins were treated as equally split percentages when multiple origins were reported (e.g., A,B as 50% each). This was correct and served well with analysing answers in the format “A” or “A,B”. However, with the introduction of explicit origin percentages per plot (e.g., C 93%, D 7%), weighting of the influence of each origin became necessary. For that, we shifted to summing and normalising these reported percentages directly to calculate weighted origin shares, allowing for a more precise representation of feed origin composition.

In addition, due to reported data inconsistencies and lacking performance we decided to exclude farmer nr 79 from our analysis. However for transparency the farmer data is still in the database.

 

Version 4 

This version has the caclulation of the average RFP of all countries changed by averaging the total RFP of each country instead of using the average of each index.

 

Version 3

In this version it has been included also the formulae used for calculating the RFP.

 

Version 2

We corrected an anonimization issue.
