Stochastic H2/H 8 Control: A Nash Game Approach - Weihai Zhang - Bog - Taylor & Francis Ltd - Plusbog.dk

The H∞ control has been one of the important robust control approaches since the 1980s. This book extends the area to nonlinear stochastic H2/H∞ control, and studies more complex and practically useful mixed H2/H∞ controller synthesis rather than the pure H∞ control. Different from the commonly used convex optimization method, this book applies the Nash game approach to give necessary and sufficient conditions for the existence and uniqueness of the mixed H2/H∞ control. Researchers will benefit from our detailed exposition of the stochastic mixed H2/H∞ control theory, while practitioners can apply our efficient algorithms to address their practical problems.

Green H2 Transport through LH2, NH3 and LOHC - Andrea Lainati - Bog - Springer International Publishing AG - Plusbog.dk

This book explores the opportunities and challenges of hydrogen transport through different carriers ( i.e. , liquefied hydrogen, ammonia, toluene, and dibenzyltoluene). Each value chain analyzed includes: renewable H2 conversion to the carrier, storage of the hydrogenated carrier, its seaborne transport, reconversion of the carrier to produce H2 and hydrogen distribution. The conversion and reconversion processes are the cost drivers of the whole value chain. These stages are investigated through an in-depth techno-economic assessment, to highlight the critical issues and the need for further investigation (low TRL). The alternatives are examined considering: different H2 applications (industrial and mobility sector); different costs of utilities (present and future scenarios); and different distances from the loading to the unloading terminal. All these scenarios are discussed and compared by means of the levelized cost method, to understand which is the most cost-effective choice for each case study. As a result, H2 application to the industrial sector shows the lowest costs, with ammonia being the best alternative for transporting and storing hydrogen in this case. Liquefied hydrogen is the most expensive H2 carrier for the industrial application, as a consequence of the high liquefaction costs while holding promises for the mobility sector.

The Chivalric Romance and the Essence of Fiction - Dani Cavallaro - Bog - McFarland & Co Inc - Plusbog.dk

Ranging from Chretien de Troyes to Shakespeare, this study proposes that the chivalric romance is characterized by a centerless structure, self-conscious fictionality and a propensity for irony. The form is tied to historical reality, yet represents the archetype of imaginative literature, declaring its fictional status without claiming to embody fixed truths. Through use of irony, the chivalric romance precludes conclusive interpretations, inviting readers to inhabit multifold fantasy worlds while uncompromisingly showing that an ideal world is only a fiction. Thus the reader is enjoined to confront the suspension of truth in their own lives.

Decarbonization of Copper Production by Optimal Demand Response and Power-to-Hydrogen - Dr Fritz Thomas Carl Roben - Bog - Verlag G. Mainz -

To avoid greenhouse gas (GHG) emissions and mitigate climate change, low-carbon technologies must be used to provide renewable energy and replace fossil fuels. However, this system transition is very material-intensive and leads to high demand for critical materials. Copper is such a material that is essential for electrical applications and many low-carbon technologies. The production of copper itself is an energyintensive process. Thus, two challenges arise that are addressed in this thesis: the flexible process operation in a fluctuating renewable energy system and the avoidance of process-based GHG emissions. The flexible operation of electricity-intensive processes can support the power grid and provide economic benefits. Demand response (DR) describes operational adjustments based on an economic incentive, such as fluctuating electricity prices. Our initial analysis shows a large DR potential of two electricity-intensive process steps in copper production. To consider the DR potential of the entire production process and to capture the dependencies of the many process steps, we formulate a detailed scheduling model of a representative copper production process. The developed mixed-integer linear program (MILP) allows minimizing the electricity costs without reducing the production volume. This process-wide scheduling enables significant DR potential, reducing annual electricity costs by up to 14.2% and shifting large parts of the electricity demand. Avoiding process-based GHG emissions is challenging because fossil fuels are hard to substitute in some processes. These processes use fossil fuels as high-temperature process heat and as chemical reducing agents. A promising alternative for these use cases is hydrogen (H2), when H2 is produced from renewable electricity using water electrolysis (Power-to-H2). The oxygen produced as a by-product offers further benefits as it can be utilized in copper production. To optimally design a power-to-H2 system, we formulate a MILP that minimizes the total annualized cost. The resulting CO2 abatement costs are 201EUR/t CO2-eq, which exceeds the current prices of EU allowances. However, a sensitivity analysis shows great potential through further development of water electrolysis. Decarbonization through Power-to-H2 offers additional DR potential. Our scheduling model of the decarbonized copper production shows that DR strongly contributes to low CO2 abatement costs. Consequently, this work identifies the potential of decarbonized copper production that provides a critical material for low-carbon technologies and supports the power grid through DR.

Patterns of Im/mobility, Conflict and Identity - - Bog - Taylor & Francis Ltd - Plusbog.dk

Patterns of im/mobility, collective identity and conflict are highly entangled. The im/mobility of a social or cultural group has major impact on how identity narratives, a sense of belonging and relationships to ‘others’ are shaped, and vice versa. These dynamics are closely interlinked with mechanisms of inclusion and exclusion between groups and power structures that involve a broad variety of actors from local populations, to migrants, government institutions and other intermediaries. Mainly looking at patterns of internal mobility such as ‘traditional’ or strategic mobilities and mobilities enforced by crisis, conflict or governmental programmes and regimes, this book aims to go beyond currently predominant issues of transnational migration. Dynamics of non/integration and belonging, caused by im/mobility, are analysed on a cultural and political level, which involves questions of representation, indigeneity/autochthony, political rights and access to land and other resources. With ethnographic case studies from Kosovo, Sierra Leone, Liberia, Bangladesh, East Timor and Indonesia, this volume provides a comparative perspective on the multifold dimensions of im/mobility in contexts where changing mechanisms of inclusion and exclusion trigger or settle conflicts and social identities are constantly re/negotiated. The chapters in this book were originally published as a special issue of Social Identities .

Model-based Design of Product, Solvent and Process for Formic Acid Synthesis from CO2 and H2 - Dr Christian Morten Jens - Bog - Verlag G. Mainz -

Today humanity faces a challenge: Global warming that is caused by emissions of CO2. To reduce CO2 emissions, usage of CO2 as a renewable carbon source has gained attention. In particular, the CO2-based synthesis of formic acid has been intensively studied, since in addition to utilizingCO2, formic acid could also act as chemical storage of fluctuating renewable energy. Developing such storage is paramount for any renewable energy system due to the fluctuating occurrence of e.g. wind. However, for the CO2-based formic acid synthesis, only a few processes have been developed. Thus, novel formic acid synthesis processes are developed in this thesis. The development considers process structure and solvents, as well as formic acid derivatives due to the unfavorable equilibrium of the CO2-based formic acid synthesis. Firstly, a process is developed for the formic acid synthesis with the widely investigated solvent dimethyl sulfoxide (DMSO). The work identifies that DMSO has an azeotrope with formic acid. To avoid the high energy demand that usually occurs in processes containing azeotropes, a novel process is developed that uses a co-solvent. Process simulations show that this novel process has an exergy demand on par with the existing state of the art CO2-based formic acid synthesis process. Secondly, a process is developed where formic acid or a derivative is used to store fluctuating renewable energy before reforming to carbon monoxide. Here, more than 100,000 combinations of formic acid derivative, solvent and process are considered by a novel design method. For the developed process, process simulations show that the exergy demand is significantly lower than for the literature benchmark. Thirdly, a novel process is developed for the synthesis of the formic acid derivative methyl formate. In this process, the supply of CO2 is integrated with the methyl formate synthesis. Usually, the CO2 supply and the synthesis are considered separate. By integrating these two steps, the energy demand and minimum selling price of methyl formate can be reduced. Finally, the thesis shows that the highest reductions in CO2 emissions and in minimum selling price are achieved with the co-solvent and the integrated methyl formate processes. Since both these processes are developed in this work, this thesis contributes towards utilization of CO2 as a raw material in chemical industries.

Handbook on Moving Corrections and Sentencing Forward - - Bog - Taylor & Francis Ltd - Plusbog.dk

This volume addresses major issues and research in corrections and sentencing with the goal of using previous research and findings as a platform for recommendations about future research, evaluation, and policy. The last several decades witnessed major policy changes in sentencing and corrections in the United States, as well as considerable research to identify the most effective strategies for addressing criminal behavior. These efforts included changes in sentencing that eliminated parole and imposed draconian sentences for violent and drug crimes. The federal government, followed by most states, implemented sentencing guidelines that greatly reduced the discretion of the courts to impose sentences. The results were a multifold increase in the numbers of individuals in jails and prisons and on community supervision—increases that have only recently crested. There were also efforts to engage prosecutors and the courts in diversion and oversight, including the development of prosecutorial diversion programs, as well as a variety of specialty courts. Penal reform has included efforts to understand the transitions from prison to the community, including federal-led efforts focused on reentry programming. Community corrections reforms have ranged from increased surveillance through drug testing, electronic monitoring, and in some cases, judicial oversight, to rehabilitative efforts driven by risk and needs assessment. More recently, the focus has included pretrial reform to reduce the number of people held in jail pending trial, efforts that have brought attention to the use of bail and its disproportionate impact on people of color and the poor. This collection of chapters from leading researchers addresses a wide array of the latest research in the field. A unique approach featuring responses to the original essays by active researchers spurs discussion and provides a foundation for developing directions for future research and policymaking.

Emplaced Resistance in Palestine and Israel - Marion Lecoquierre - Bog - Taylor & Francis Ltd - Plusbog.dk

The Israeli-Palestinian conflict gravitates constantly around the question of territorial control due to the settler-colonial principle present at the core of the Zionist project. Acknowledging space as a central tool of domination used by the Israeli authorities, this volume sheds light on the way space can become both a resource for and an outcome of protest, with an emphasis placed on the way it is used and produced through practices of resistance by subaltern groups. The research relies on a comparative approach, relying on data collected in the course of fieldwork conducted between 2012 and 2015 in Palestine and Israel. It focuses on three "sites of contention", which include the H2 area in Hebron (the occupied Old City, under Israeli authority), the "core" neighbourhoods of Silwan (Wadi Hilwe and al-Bustan) and the unrecognized Bedouin village of al-Araqib, in the Negev desert. Through these three case studies, the book tackles different strategies that engage with the materiality of space, place, sense of place, territory, landscape, network and scale, showing the mobilization of a real "spatial repertoire" of contention. The different regimes of control give rise to strategies that are first and foremost emplaced , i.e. rooted in the local. Providing an original comparison between flashpoints of the Palestinian resistance against the Israeli politics of dispossession and expulsion, the book is a key resource for scholars and readers interested in political geography, political science, sociology, and the Israel-Palestine conflict.

Immobilization of Ruthenium-Triphos Catalysts and their Application for the Hydrogenation of Polar Bonds in Batch and Continuous-Flow Systems - Dr

The present thesis deals with the development of immobilized Ruthenium-Triphos catalysts for the selective hydrogenation of esters, amides and CO2 as potential substrates in the context of the valorization of renewable carbon resources. The highly active molecular catalyst [Ru(Triphos)TMM] (C-1a), already investigated in various catalytic approaches and mechanistic studies, was defined as target structure for immobilization. In a detailed preparative study, two synthetic pathways towards [(Ru(Ether-Triphos)TMM] (C-2a) and [(Ru(Carbamate-Triphos)TMM] (C-3a) were developed, using a triethoxysilyl-functionality as anchoring-group in the catalysts backbone, enabling the covalent immobilization on oxidic supports (section 3.1). Subsequently, the complex [(Ru(Ether-Triphos)TMM] (C-2a) was tethered on amorphous SiO2,500, leading to the heterogenized catalyst [(Ru(Ether-Triphos)TMM]@SiO2,500 (C-2b, section 3.1). The immobilized catalyst was successfully tested in ester-, amide- and CO2 hydrogenation reactions in single-batch and continuous-flow experiments. In lactam hydrogenation reactions the immobilized catalyst showed superior long-term stability and activity in comparison to its homogeneous counterpart. Since the homogeneous complex quickly forms an inactive hydridebridged dimer under the employed reaction conditions, the active-site isolation of the tethered complexes on the surface prevents self-deactivation, thus maintaining its activity in several recycling steps. For long-term continuous-flow hydrogenation tests with C-2b, DL-lactide was evaluated as a suitable benchmark-substrate in an extensive ester screening. Here, different catalyst pre-treatments were tested to maximize catalyst activity. High TON ( 4700) over multiple days in flow were reached and the changes that the catalyst material underwent were characterized (section 3.3). After the catalytic evaluation of C-2b the observed Ru leaching was determined to be the major target for further catalyst optimization. Therefore, various modifications in catalyst preparation were performed, including changes in the synthesis order and reaction conditions, additive utilization as well as the incorporation of the complex C-2a into the framework mesostructured SBA-15 towards [(Ru(Ether-Triphos)TMM]@SBA-15 (C-2k, section 3.4). In a final investigation, selected catalysts were evaluated in the direct synthesis of dimethoxy methane (DMM) from CO2, H2 and MeOH. Catalyst C-2k was highly active and superior in terms of low Ru leaching-rates and reached unpreceded activity during recycling experiments (TON 1900 of DMM, section 3.5).

Life-Cycle Assessment of Low-Carbon Technologies from Screening to Integrated Energy System Design - Dr Sarah Deutz - Bog - Verlag G. Mainz -

Climate change mitigation requires a massive reduction of greenhouse gas (GHG) emissions and even negative emissions in the near future. To achieve GHG mitigation, low-carbon technologies are developed. However, environmental benefits are not generally proven since most technologies require significant amounts of low-carbon energy and interact in complex energy systems. Moreover, low-carbon technologies comprise a wide range of maturity and varying data availability. Assessing the full range of low-carbon technologies requires life-cycle assessment (LCA), from screening to an integrated energy system design at the concept, process, plant to system level. At the concept level, we demonstrate handling of limited data availability and apply an LCA-based short-cut method enabling a best-case ranking of CO2-based chemicals. Half of these products have the potential to provide environmental benefits already today through shortened synthetic pathways and low H2 demand. In contrast, the other products could only achieve environmental benefits when sufficient low-carbon electricity is available. Using a process from the best-case ranking, we expand the LCA model scope to the process level providing a more detailed environmental assessment for the example of CO2-based oxymethylene ethers (OME) fuels. Our well-to-wheel analysis shows a significant potential to decrease local pollutants, whereas climate impacts are only reduced if large amounts of low-carbon energy are available. Subsequently, we extend the LCA model scope to the plant level exemplary for direct air capture (DAC). We demonstrate that climate benefits strongly depend on the electricity supply and the subsequent application of CO2: permanent storage leads to negative emissions, whereas using CO2 as feedstock for fuels could reach carbon neutrality at best. Furthermore, large-scale deployment of DAC, e. g., capturing 1% of global annual CO2 emissions, will not be limited by energy and materials requirements and will increase other environmental impacts by much less than 1%. Our analyses emphasize the environmental potential of low-carbon technologies and their dependence on low-carbon energy; however, neglecting their cross-sectoral interconnectivity in the energy system. Therefore, we extend the scope of LCA to the system level by developing an energy system model with integrated LCA. The computed low-carbon transition pathways lead to many co-benefits in other environmental impact categories but also cause burden-shifting, which needs to be considered when developing climate mitigation strategies.
