Gamification for sustainable food transitions: supporting multi-level cooperation in short food supply chains through GAIN

open access: yesInternational Journal of Food Studies, 2022
The food system has become globalized and industrial. As a consequence, food travels long distances to reach consumers and its production is over-reliant on chemicals, leading to high levels of carbon emissions and soil degradation.

FPGA-based prototyping of IEEE 802.11a base band processor [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2004
In technical literature and especially in domestic, predominant way to examine performance of 802.11a-based systems are experiments in simulations. In this paper, we present FPGA based 802.11a prototype, which gave us a possibility to gain closer insight

Integrating Fiber Sensing for Spatially Resolved Temperature Measurement in Fuel Cells

open access: yesEnergies, 2023
Fiber optic sensors integrated into fuel cell stacks have the potential to significantly enhance the temperature control and health monitoring of fuel cells. Inhomogeneous loading, both within individual cells and across different cells in a stack, leads

An Architectural Perspective on Sketching

open access: yesJournal of Traditional Building, Architecture and Urbanism, 2023
Architects often rely heavily on hand-sketching to represent their ideas to others, but many have never formally studied what makes a good perspective sketch.

Exergy Analysis of the Prevailing Residential Heating System and Derivation of Future CO2-Reduction Potential

open access: yesEnergies, 2022
The residential heating sector accounts for a large share of the worldwide annual primary energy consumption. In order to reduce CO2-emissions, it is therefore particularly important to analyse this sector for potential efficiency improvements. In Europe,

Experimental Analysis of the Long-Term Stability of Thermoelectric Generators under Thermal Cycling in Air and Argon Atmosphere

open access: yesEnergies, 2023
It is estimated that 72% of the worldwide primary energy consumption is lost as waste heat. Thermoelectric Generators (TEGs) are a possible solution to convert a part of this energy into electricity and heat for space heating.

The ecology of management concepts [PDF]

open access: yes, 2020
How does the popularity of a concept depend on how it contrasts with and complements existing concepts? We argue that being similar to existing concepts, being located in a popular domain, and being combined with similar existing concepts are important ...

3 kW Thermoelectric Generator for Natural Gas-Powered Heavy-Duty Vehicles—Holistic Development, Optimization and Validation

open access: yesEnergies, 2021
Emissions from heavy-duty vehicles need to be reduced to decrease their impact on the climate and to meet future regulatory requirements. The use of a cost-optimized thermoelectric generator based on total cost of ownership is proposed for this vehicle ...

Challenges in the (Re-)Connection of Peripheral Areas to the Rail Network from a Rolling Stock Perspective: The Case of Germany

open access: yesVehicles, 2023
Currently, in the course of the German mobility transition, an increasing number of disused rail lines are already being or intended to be reactivated in order to increase capacities, decrease transport-related emissions and reconnect rural areas to ...
