description Publicationkeyboard_double_arrow_right Article 2023 GermanyPublisher:Elsevier BV Funded by:EC | BioMatesEC| BioMatesAuthors: Lukáš Kejla; Tim Schulzke; Pavel Šimáček; Miloš Auersvald;Lukáš Kejla; Tim Schulzke; Pavel Šimáček; Miloš Auersvald;Carbohydrates are a group of compounds abundantly present in pyrolysis bio-oils. Their quantitative analysis however presents many challenges such as possible co-elution with other oxygenates when liquid chromatographic methods are used. For a cheaper and faster analysis, spectrophotometric methods are a convenient alternative. Most of the absorption spectrometry-based methods stem from the reaction scheme, where the carbohydrates are converted into furfural or 5-hydroxymethylfurfural (HMF) derivatives and simultaneously react with colorizing agents such as phenol or anthrone. Alternatively, the produced compounds can be determined in the UV region without the addition of colorizing agent. An obvious problem arises when these furanic compounds are already present in the mixture, which is the case with most biomass-based pyrolysis bio-oils. In this study, we quantified the responses of 26 potential interferents that are expected to be present in the water-soluble fraction of bio-oils as well as 13 different carbohydrates. To mitigate the interferences, we used styrene-divinylbenzene polymeric resin adsorbents to separate the less polar interferents from the aqueous bio-oil extract and naturally formed bio-oil aqueous phases. A derivatization-GC-MS method was used as a reference for comparison of the results. We found that the adsorption step is crucial for acquiring more precise and accurate results. The anthrone method was the least susceptible to interferences and simultaneously produced results that were the closest to the reference GC-MS method. Statistical analysis showed no significant differences between the optimized anthrone method and the reference GC-MS method.

Amditis;Mixed traffic of conventional and automated vehicles entails many challenges concerning the safe coexistence and the improvement of traffic efficiency. As a solution, a Traffic Management Center (TMC) combines information from physical sensors and communicated data to enable advanced traffic controllers. Since there is no sufficient penetration rate of automated vehicles nowadays, such a solution could be developed and tested with synthetically generated data using simulation, which models the future Intelligent Transportation System (ITS). This paper addresses the challenges for evaluation of such a system by the means of simulation. For this purpose, we present the Eclipse MOSAIC Multi-Domain Simulation Framework, which provides the possibility to couple best-in-class simulators of the domains traffic, application, and communication, as well as to include further models and external native code libraries. Moreover, we discuss modeling extensions for traffic control algorithms and our method to create a highway scenario based on real traffic data. As primary result, many research questions for mixed traffic and ITS could be investigated using the MOSAIC framework. In an exemplary study, we analyze the deployment effort for infrastructure and communication technologies in order to facilitate a Mainstream Traffic Flow Controller in a realistic scenario with mixed traffic. Simulations performed with MOSAIC confirmed that traffic efficiency improvement is feasible even with fewer infrastructure components, thus with less cost.

In this study, we present results of an in situ stress state estimation for the Los Humeros geothermal field (Mexico) located in the eastern section of the Trans-Mexican Volcanic Belt. During more than 40 years of geothermal energy production, issues related to induced seismicity, reservoir depletion, subsidence, and wellbore stability have occurred in Los Humeros. The in situ stress tensor, being one of the major controls on the above-mentioned phenomena, remains highly uncertain. The high temperatures of the geothermal reservoir at Los Humeros, often exceeding the critical point of water, promote difficulties in performing in situ stress measurements. In this study, based on data commonly acquired from drilling operations from eleven high-temperature wells within the Los Humeros caldera, we constrain the in situ stress state of the geothermal field. For this purpose, we employ borehole observations including borehole breakouts, instances of fluid circulation loss, and injection tests. Results from this study indicate predominantly strike-slip regime with a strong reverse component and NE-SW acting maximum horizontal stress. Utilizing slip and dilation tendency analysis, permeability and seismic activity of major fault zones within the geothermal field could be aptly explained by the acting stress regime. The outcome of this study provides valuable insights into the in situ stress state of the Los Humeros caldera and supports the exploration of conventional and unconventional (i.e., supercritical) geothermal resources.

This is possible with a suitable human-machine interface (HMI). In this driving simulator study, two visual HMI concepts (Concept A and B ) were compared with a baseline for informing drivers about three modes: manual driving, assisted driving, and automated driving. The HMIs, consisting of LED strips on the steering wheel that differed in luminance, color, and pattern, provided continuous information about the active mode and announced transitions. The assisted mode was conveyed in Concept A using a combination of amber and blue LEDs, while in Concept B only amber LEDs were used. During automated driving Concept A displayed blue LEDs and Concept B, turquoise. Both concepts were compared to a baseline HMI, with no LEDs. Thirty-eight drivers with driving licence were trained and participated. Objective measures (hands-on-wheel time, takeover time, and visual attention) are reported. Self-reported measures (mode awareness, trust, user experience, and user acceptance) from a previous publication are briefly repeated in this context (Muthumani et al.). Concept A showed 200 ms faster hands-on-wheel times than the baseline, while in Concept B several outliers were observed that prevented significance. The visual HMIs with LEDs did not influence the eyes-on-road time in any of the automation levels. Participants preferred Concept B, with more prominent differentiation between the automation levels, over Concept A.

The objective of this investigation was to identify variables of industrially relevant extraction processes that increase the purity of hemicelluloses extracted from fruit residues. Our main finding is that extraction with subcritical water, followed by precipitation with alcohol, can be adjusted to yield products with a purity of at least 90%. Purity was determined based on the total concentration of glucose, galactose, xylose, arabinose, and mannose after hydrolysis with sulfuric acid. In the first experimental design (DoE methodology), the effects of extraction temperature (95-155 °C) and time (20-100 min) on yield and purity were studied. A clear trade-off between yield and purity was observed at high temperatures, indicating the selective removal of impurities. In the second experimental design, the influence of extract pH and alcohol concentration on yield and purity was investigated for the raw extract and a concentrate of this extract with 1/6 of the original volume. The concentrate was obtained by ultrafiltration through ceramic hollow-fiber membranes. The highest purity of 96% was achieved with the concentrate after precipitating with 70% alcohol. Key factors for the resource efficiency of the overall process are addressed. It is concluded that extraction with subcritical water and ultrafiltration are promising technologies for producing hemicelluloses from fruit residues for material applications.

Two advanced parameter identification methodologies - ParaID by Fraunhofer ISE and RealTrackEff by the Cyprus Institute - are compared in terms of the underlying equations, which extend ISO 9806. Both approaches are then applied to a Linear Fresnel collector research facility at the Cyprus Institute, for which a database of more than 50 measurement days is available, including reflectometric measurements. For both methods, several variations with increasing complexity are tested and the quality of the resulting fit in terms of outlet temperature is studied. Both methods take into account soiling/cleanliness and non- linear collector behavior. While ParaID focuses on the identification of the IAMs in a real environment, the method by the Cyprus Institute links the efficiency to non-linear tracking effects. Real collector characteristics like varying cleanliness and asymmetric collector behavior are found to have a strong impact on the collector performance and the identified parameters. For the ParaID approach, additional results regarding confidence intervals based on Bootstrapping and regarding identified Incidence Angle Modifiers are presented.

Air quality prediction with black-box (BB) modelling is gaining widespread interest in research and industry. This type of data-driven models work generally better in terms of accuracy but are limited to capture physical, chemical and meteorological processes and therefore accountability for interpretation. In this paper, we evaluated different white-box (WB) and BB methods that estimate atmospheric black carbon (BC) concentration by a suite of observations from the same measurement site. This study involves data in the period of 1st January 2017–31st December 2018 from two measurement sites, from a street canyon site in Mäkelänkatu and from an urban background site in Kumpula, in Helsinki, Finland. At the street canyon site, WB models performed (R² = 0.81–0.87) in a similar way as the BB models did (R² = 0.86–0.87). The overall performance of the BC concentration estimation methods at the urban background site was much worse probably because of a combination of smaller dynamic variability in the BC values and longer data gaps. However, the difference in WB (R²= 0.44–0.60) and BB models (R² = 0.41–0.64) was not significant. Furthermore, the WB models are closer to physics-based models, and it is easier to spot the relative importance of the predictor variable and determine if the model output makes sense. This feature outweighs slightly higher performance of some individual BB models, and inherently the WB models are a better choice due to their transparency in the model architecture. Among all the WB models, IAP and LASSO are recommended due to its flexibility and its efficiency, respectively. Our findings also ascertain the importance of temporal properties in statistical modelling. In the future, the developed BC estimation model could serve as a virtual sensor and complement the current air quality monitoring. Peer reviewed

It was conducted in South France, one of the most touristic European regions, and also one of the regions at the highest forest fire risk that is projected to be amplified under future climate conditions. The case study has been implemented through a co-creation framework with local stakeholders, which is critical in moving beyond physical damages to the infrastructures, introducing the elements of infrastructure business continuity and societal resilience. Future forest fires extremes are anticipated to impact the interconnections of electricity and transportation networks that could further cascade to communities throughout South France. The work highlighted the benefits of enhancing co-operation between academia, emergency responders, and infrastructure operators as a critical element in enhancing resilience through increased awareness of climate impacts, new generated knowledge on fire extremes and better cooperation between involved agencies.

Cost efficient climate change mitigation requires installing a total of 20-80 TWp photovoltaics until 2050 and 80-170 TWp until 2100. The question is, whether the projected growth is feasible from a resource point of view - and if so, under which conditions. We assess demand for fundamental resources until the year 2100, which are necessary independently from the specific nature of the used PV technology, i.e. energy, float-glass, and capital investments, and addtionally silver. Without technological learning serious resource constraints will arise. On the other hand, continued technological learning at current rates would be sufficient to stay within reasonable boundaries. With such technological learning, energy demand for production will correspond to 2-5% of global energy consumption leading to cumulative greenhouse gas emissions of 4-11% of the 1.5 °C emission budget. Glass demand might still exceed current float-glass production, requiring capacity expansion; and silver consumption could be kept at current levels. Installations costs would be 300-600 billion $US2020 per year. Technological solutions enabling such learning are foreseeable, nevertheless current and future investments must not only be targeted at capacity expansion but also at upholding the currently high rate of innovation.

Their quantitative analysis however presents many challenges such as possible co-elution with other oxygenates when liquid chromatographic methods are used. For a cheaper and faster analysis, spectrophotometric methods are a convenient alternative. Most of the absorption spectrometry-based methods stem from the reaction scheme, where the carbohydrates are converted into furfural or 5-hydroxymethylfurfural (HMF) derivatives and simultaneously react with colorizing agents such as phenol or anthrone. Alternatively, the produced compounds can be determined in the UV region without the addition of colorizing agent. An obvious problem arises when these furanic compounds are already present in the mixture, which is the case with most biomass-based pyrolysis bio-oils. In this study, we quantified the responses of 26 potential interferents that are expected to be present in the water-soluble fraction of bio-oils as well as 13 different carbohydrates. To mitigate the interferences, we used styrene-divinylbenzene polymeric resin adsorbents to separate the less polar interferents from the aqueous bio-oil extract and naturally formed bio-oil aqueous phases. A derivatization-GC-MS method was used as a reference for comparison of the results. We found that the adsorption step is crucial for acquiring more precise and accurate results. The anthrone method was the least susceptible to interferences and simultaneously produced results that were the closest to the reference GC-MS method. Statistical analysis showed no significant differences between the optimized anthrone method and the reference GC-MS method.

Amditis;Mixed traffic of conventional and automated vehicles entails many challenges concerning the safe coexistence and the improvement of traffic efficiency. As a solution, a Traffic Management Center (TMC) combines information from physical sensors and communicated data to enable advanced traffic controllers. Since there is no sufficient penetration rate of automated vehicles nowadays, such a solution could be developed and tested with synthetically generated data using simulation, which models the future Intelligent Transportation System (ITS). This paper addresses the challenges for evaluation of such a system by the means of simulation. For this purpose, we present the Eclipse MOSAIC Multi-Domain Simulation Framework, which provides the possibility to couple best-in-class simulators of the domains traffic, application, and communication, as well as to include further models and external native code libraries. Moreover, we discuss modeling extensions for traffic control algorithms and our method to create a highway scenario based on real traffic data. As primary result, many research questions for mixed traffic and ITS could be investigated using the MOSAIC framework. In an exemplary study, we analyze the deployment effort for infrastructure and communication technologies in order to facilitate a Mainstream Traffic Flow Controller in a realistic scenario with mixed traffic. Simulations performed with MOSAIC confirmed that traffic efficiency improvement is feasible even with fewer infrastructure components, thus with less cost.

In this study, we present results of an in situ stress state estimation for the Los Humeros geothermal field (Mexico) located in the eastern section of the Trans-Mexican Volcanic Belt. During more than 40 years of geothermal energy production, issues related to induced seismicity, reservoir depletion, subsidence, and wellbore stability have occurred in Los Humeros. The in situ stress tensor, being one of the major controls on the above-mentioned phenomena, remains highly uncertain. The high temperatures of the geothermal reservoir at Los Humeros, often exceeding the critical point of water, promote difficulties in performing in situ stress measurements. In this study, based on data commonly acquired from drilling operations from eleven high-temperature wells within the Los Humeros caldera, we constrain the in situ stress state of the geothermal field. For this purpose, we employ borehole observations including borehole breakouts, instances of fluid circulation loss, and injection tests. Results from this study indicate predominantly strike-slip regime with a strong reverse component and NE-SW acting maximum horizontal stress. Utilizing slip and dilation tendency analysis, permeability and seismic activity of major fault zones within the geothermal field could be aptly explained by the acting stress regime. The outcome of this study provides valuable insights into the in situ stress state of the Los Humeros caldera and supports the exploration of conventional and unconventional (i.e., supercritical) geothermal resources.

This is possible with a suitable human-machine interface (HMI). In this driving simulator study, two visual HMI concepts (Concept A and B ) were compared with a baseline for informing drivers about three modes: manual driving, assisted driving, and automated driving. The HMIs, consisting of LED strips on the steering wheel that differed in luminance, color, and pattern, provided continuous information about the active mode and announced transitions. The assisted mode was conveyed in Concept A using a combination of amber and blue LEDs, while in Concept B only amber LEDs were used. During automated driving Concept A displayed blue LEDs and Concept B, turquoise. Both concepts were compared to a baseline HMI, with no LEDs. Thirty-eight drivers with driving licence were trained and participated. Objective measures (hands-on-wheel time, takeover time, and visual attention) are reported. Self-reported measures (mode awareness, trust, user experience, and user acceptance) from a previous publication are briefly repeated in this context (Muthumani et al.). Concept A showed 200 ms faster hands-on-wheel times than the baseline, while in Concept B several outliers were observed that prevented significance. The visual HMIs with LEDs did not influence the eyes-on-road time in any of the automation levels. Participants preferred Concept B, with more prominent differentiation between the automation levels, over Concept A.

The objective of this investigation was to identify variables of industrially relevant extraction processes that increase the purity of hemicelluloses extracted from fruit residues. Our main finding is that extraction with subcritical water, followed by precipitation with alcohol, can be adjusted to yield products with a purity of at least 90%. Purity was determined based on the total concentration of glucose, galactose, xylose, arabinose, and mannose after hydrolysis with sulfuric acid. In the first experimental design (DoE methodology), the effects of extraction temperature (95-155 °C) and time (20-100 min) on yield and purity were studied. A clear trade-off between yield and purity was observed at high temperatures, indicating the selective removal of impurities. In the second experimental design, the influence of extract pH and alcohol concentration on yield and purity was investigated for the raw extract and a concentrate of this extract with 1/6 of the original volume. The concentrate was obtained by ultrafiltration through ceramic hollow-fiber membranes. The highest purity of 96% was achieved with the concentrate after precipitating with 70% alcohol. Key factors for the resource efficiency of the overall process are addressed. It is concluded that extraction with subcritical water and ultrafiltration are promising technologies for producing hemicelluloses from fruit residues for material applications.

Two advanced parameter identification methodologies - ParaID by Fraunhofer ISE and RealTrackEff by the Cyprus Institute - are compared in terms of the underlying equations, which extend ISO 9806. Both approaches are then applied to a Linear Fresnel collector research facility at the Cyprus Institute, for which a database of more than 50 measurement days is available, including reflectometric measurements. For both methods, several variations with increasing complexity are tested and the quality of the resulting fit in terms of outlet temperature is studied. Both methods take into account soiling/cleanliness and non- linear collector behavior. While ParaID focuses on the identification of the IAMs in a real environment, the method by the Cyprus Institute links the efficiency to non-linear tracking effects. Real collector characteristics like varying cleanliness and asymmetric collector behavior are found to have a strong impact on the collector performance and the identified parameters. For the ParaID approach, additional results regarding confidence intervals based on Bootstrapping and regarding identified Incidence Angle Modifiers are presented.

Air quality prediction with black-box (BB) modelling is gaining widespread interest in research and industry. This type of data-driven models work generally better in terms of accuracy but are limited to capture physical, chemical and meteorological processes and therefore accountability for interpretation. In this paper, we evaluated different white-box (WB) and BB methods that estimate atmospheric black carbon (BC) concentration by a suite of observations from the same measurement site. This study involves data in the period of 1st January 2017–31st December 2018 from two measurement sites, from a street canyon site in Mäkelänkatu and from an urban background site in Kumpula, in Helsinki, Finland. At the street canyon site, WB models performed (R² = 0.81–0.87) in a similar way as the BB models did (R² = 0.86–0.87). The overall performance of the BC concentration estimation methods at the urban background site was much worse probably because of a combination of smaller dynamic variability in the BC values and longer data gaps. However, the difference in WB (R²= 0.44–0.60) and BB models (R² = 0.41–0.64) was not significant. Furthermore, the WB models are closer to physics-based models, and it is easier to spot the relative importance of the predictor variable and determine if the model output makes sense. This feature outweighs slightly higher performance of some individual BB models, and inherently the WB models are a better choice due to their transparency in the model architecture. Among all the WB models, IAP and LASSO are recommended due to its flexibility and its efficiency, respectively. Our findings also ascertain the importance of temporal properties in statistical modelling. In the future, the developed BC estimation model could serve as a virtual sensor and complement the current air quality monitoring. Peer reviewed

It was conducted in South France, one of the most touristic European regions, and also one of the regions at the highest forest fire risk that is projected to be amplified under future climate conditions. The case study has been implemented through a co-creation framework with local stakeholders, which is critical in moving beyond physical damages to the infrastructures, introducing the elements of infrastructure business continuity and societal resilience. Future forest fires extremes are anticipated to impact the interconnections of electricity and transportation networks that could further cascade to communities throughout South France. The work highlighted the benefits of enhancing co-operation between academia, emergency responders, and infrastructure operators as a critical element in enhancing resilience through increased awareness of climate impacts, new generated knowledge on fire extremes and better cooperation between involved agencies.

Cost efficient climate change mitigation requires installing a total of 20-80 TWp photovoltaics until 2050 and 80-170 TWp until 2100. The question is, whether the projected growth is feasible from a resource point of view - and if so, under which conditions. We assess demand for fundamental resources until the year 2100, which are necessary independently from the specific nature of the used PV technology, i.e. energy, float-glass, and capital investments, and addtionally silver. Without technological learning serious resource constraints will arise. On the other hand, continued technological learning at current rates would be sufficient to stay within reasonable boundaries. With such technological learning, energy demand for production will correspond to 2-5% of global energy consumption leading to cumulative greenhouse gas emissions of 4-11% of the 1.5 °C emission budget. Glass demand might still exceed current float-glass production, requiring capacity expansion; and silver consumption could be kept at current levels. Installations costs would be 300-600 billion $US2020 per year. Technological solutions enabling such learning are foreseeable, nevertheless current and future investments must not only be targeted at capacity expansion but also at upholding the currently high rate of innovation.
