description: The need for cost-effective and flexible solutions to compose the distributed energy storage makes second-life lithium-ion batteries (SLIB) a discussed option. The SLIB is a lithium-ion battery used in an energy/power-intensive first application (automotive) that still retains important performance characteristics to have a second-life application. SLIBs can represent an opportunity to meet this demand and an option for residential and off-grid applications, presenting competitive cost advantages over new batteries. However, their application within the current state of the art still needs to overcome several challenges to become technically and economically viable. In the framework of the POCITYF project (GA 864400), a prototype of a SLIB from the company betteries AMPS GmbH has been tested at the University of Évora, connected to the existing experimental microgrid through a commercial inverter. This work aims to contribute to the state of the art of SLIB technology, providing insights into their electrical performance and presenting technical key performance indicators in a real-operational environment. This enables the further finetuning and validation of the product, reaching a higher TRL. This work aims to improve technology acceptance by demonstrating safety and reliability under real operating conditions and promoting the ease of installation and operation of these technologies.

In this framework, in this work we: a) describe a thermodynamic analysis that can assist to screen which solar fuel production could be economically feasible from basic principles as well as to estimate the minimum amount of energy required to capture CO2 from air; b) we review an electrochemical process, based mainly on the use of dehydrogenases and nicotine adenine dinucleotide, that could be used to convert CO2 into methanol and c) an electrochemical process suitable for capturing CO2 from ambient air.
Developing a performance-enhancing Road Maintenance Decision Support System (RMDSS) for developing countries

Subjects: Other built environment and design not elsewhere classified

description: An important aspect of infrastructure management is an awareness of the consequences of inadequate maintenance protocols for ensuring the economic viability of the assets. In the road sector, this is of prime importance as roads underpin practically all transport related activities in every economy. A review of maintenance management of infrastructure, with particular reference to roads, exposed an inadequate level of expenditure or poor management of the road network, which often has severe implications for the economic and social well-being of a country, especially seen in Vehicle Operating Costs (VOC), accident costs, travel time costs, and associated environmental impact. The performance of road maintenance management systems can be judged by some essential indicators such as cost, safety, environmental impact and level of complaints by users. With particular reference to the developing countries, there has been an overwhelming emphasis on the under-performance of existing road maintenance management systems. Such under-performance can be linked to the management of available assets, which often presents in the form of deferment of maintenance work and consequential accumulation of maintenance backlogs. The lack of appropriate decision support systems (DSS) adds to the problem as executives often have difficulty to reconcile several factors that influence their choice of a solution to enhance decision-making. Furthermore, the non-existence of a suitable road network database along with a lack of coordination and integration between different management levels and sections involved in the decisions exacerbates the problem. The availability of computing technology makes the option of using a data-driven computer-based solution or decision support system (DSS) a viable one for many roads maintenance executives in developing countries. To achieve such a data-driven solution, various methods were adopted in this research, including a literature review, and a source-context questionnaire survey. The data mobilised from the survey was complemented by Bayesian Networks to accomplish a suitable DSS that responds to the sources covered by the study. This study resulted in the development and implementation of an optimisation Road Maintenance Decision Support System (RMDSS) to enable executives in the roads sector to make more effective and efficient decisions that relate to the maintenance of road assets. Testing and validation of the RMDSS indicated great potential for making maintenance management decisions more effective and proactive when faced with budgets and other operational constraints.

description: We present a novel proposal for generating quantum superpositions of macroscopically distinct states of a bulk mechanical oscillator, compatible with existing optomechanical devices operating in the readily achievable bad-cavity limit. The scheme is based on a pulsed cavity optomechanical quantum non-demolition (QND) interaction, driven by displaced non-Gaussian states, and measurement-induced feedback, avoiding the need for strong single-photon optomechanical coupling. Furthermore, we show that single-quadrature cooling of the mechanical oscillator is sufficient for efficient state preparation, and we outline a three-pulse protocol comprising a sequence of QND interactions for squeezing-enhanced cooling, state preparation, and tomography.

description: Photovoltaic (PV) inverters convert DC power to AC power. Inverters typically employ maximum power point tracking (MPPT) algorithms to maximize power production. Many modern inverters support several independent MPPT inputs to maximize energy production from arrays with different configurations or orientations. There is no consensus test procedure for evaluating the DC-to-AC conversion efficiency for multi-input inverters. Herein, we propose a test procedure based on the open-source System Validation Platform (SVP) software. We apply the procedure to a commercial inverter with six MPPT inputs to demonstrate that the resulting measurements can be used to fit a model that predicts inverter power at all conditions with reasonable accuracy.

description: Multimodal transport system is modern transport and freight distribution system all over the world is tending towards the adoption of best practices, those are reliable, timely and cost effectively. Multimodal transport between sea, road and rail, has received a large interest in recent years. Hence, this research focusedon the determinants factors of multimodal transport effectiveness. And then how these factors affect multimodal effectiveness. Primary data were collected witha structured questionnaire and interview as a data collection instrument was usedandsupported by secondary data. Out of the 228 questionnaires distributed only 200 were successfully returned back. Descriptive and inferential statistics analysis method were used to analysis the outputs (i.e. mean, ANOVA, t-tests and regression) using SPSS Software. Five determinant factors of multimodal effectiveness (i.e. transitcost, transit time, logisticsinfrastructures, services reliability and cargo safety and liability) were analyzed. Based on the findings of the research most of the respondents were dissatisfied on fairness of transit cost, moderately agreed on the infrastructures, service reliability and transit time, and agree on the cargo safety and liability.Hence, based on the findings of the research it is possible to conclude that shortages of logistics infrastructures which result in increased transit cost and time.It also indicate that transit cost, transit time, logistics infrastructure and service reliabilityhave significant impact on multimodal effectiveness. In addition, least square regression showed that 65 percentage of the variability of multimodal effectiveness was explained by the independent variables. Lastly, the researcher recommends Ethiopian Shipping Logistics Service Enterprise, should improve information technology infrastructures and equipped all the ports and terminalslatest machineries and facilities in the future. Furthermore, remove double costs and should provide one stop services for the effectiveness of multimodal transport system. Key Words: Multimodal Transport System, transit cost and time, dry Ports

description: The aim of this work is to provide a guide for the design of a photovoltaic plus battery energy storage system coupled with a heat pump for different locations and thus different climates in Europe. Through a multi-objective optimization approach applied to the six European geoclusters and applying different solution selection criteria, it was possible to obtain the optimal photovoltaic nominal power (kWp) normalized over the thermal consumption of a reference building and the optimal capacity of the battery per kWp of photovoltaic (kWh:kWp) installed. Due to the normalization process, results can be generalized and can be used for designing similar systems in all buildings around Europe. The results of this work must be intended as a support for designers for the early-design phase of such systems or as an initial guess for an iterative process in more advanced evaluations.

description: At the heart of systems chemistry lies the idea that supramolecular interactions can give rise to complex and unexpected collective states that emerge on a fundamentally different lengthscale to that of the interactions themselves. While in certain cases - e.g. the self-assembly of virus-like polyhedral cages from coordination building blocks - it is possible to control emergence in a systematic manner, the development of general approaches remains a fundamental challenge in the field. In the conceptually-related domain of frustrated magnetism - where collective states give rise to exotic physics of relevance to data storage and spintronics - the task of predicting emergent behaviour is simplified through control over the geometry and form of the magnetic interactions from which complexity arises. Seeking to combine approaches from these two fields, we study here the solid phases of inorganic polymer chains assembled from non-magnetic gold(I)/silver(I) cations and cyanide anions. We show the periodic inter-chain potential encodes a supramolecular interaction that can be tuned to mimic different magnetic interactions between XY spins ("spin rotors"). Because the chains pack on a triangular lattice, the crystal structures of gold(I)/silver(I) cyanides can be interpreted in terms of the phase behaviour of triangular XY magnets. Complex magnetic states predicted for this family - including hidden quadrupolar order and emergent spin-vortex quasiparticles - are realised for the first time in the structural chemistry of these cyanide polymers. In this way we demonstrate both how simple inorganic materials might behave as structural analogues of otherwise-unrealisable "toy" spin models, and also how a theoretical understanding of those models might be used to predict and control emergent phenomena in chemical systems.

description: Solar water pumping combines solar photovoltaic (PV) technologies, hydraulic engineering, and high-efficiency technology to provide water management techniques and optimise irrigated farming. Within the context of the SolaQua project, a solar photovoltaic system design for water pumping was developed and implemented in Montes Velhos Pumping Station, located in Aljustrel, Portugal. This pumping station has 2.813 MW of total installed pumping power and a maximum flow rate of 3.08 m3 /s. The designed PV system has 320 kWp installed on 1-axis North-South horizontal sun-trackers in a hybridised configuration with the electricity grid. This work aims to analyse the real operation data from that hydro-agricultural system from 2019 to May 2022. It is intended to analyse data regarding the electrical conversion efficiency of the pumping station, to calculate the annual performance ratio (PR) and other equally relevant variables for the pumping station and solar photovoltaic plants, such as self-consumption rates and annual savings. The designed system allowed the cost reduction of the pressurised pumped water and increased the share of renewable energy (RE), presenting a cost-effective alternative to the previous energy sources, diesel generators or electric grid for water pumping.

description: Autonomous vehicles have gained substantial traction as the future of transportation, necessitating continuous research and innovation. While 2D object detection and instance segmentation methods have made significant strides, 3D object detection offers unparalleled precision. Deep neural network-based 3D object detection, coupled with sensor fusion, has become indispensable for self-driving vehicles, enabling a comprehensive grasp of the spatial geometry of physical objects. In our study of a Lidar-based 3D object detection network using point clouds, we propose a novel architectural model based on You Only Look Once (YOLO) framework. This innovative model combines the efficiency and accuracy of the YOLOv8 network, a swift 2D standard object detector, and a state-of-the-art model, with the real-time 3D object detection capability of the Complex YOLO model. By integrating the YOLOv8 model as the backbone network and employing the Euler Region Proposal (ERP) method, our approach achieves rapid inference speeds, surpassing other object detection models while upholding high accuracy standards. Our experiments, conducted on the KITTI dataset, demonstrate the superior efficiency of our new architectural model. It outperforms its predecessors, showcasing its prowess in advancing the field of 3D object detection in autonomous vehicles.

description: The purpose of this paper is to analyse the performance of photovoltaic (PV) systems and evaluate the energy output of various PV system configurations and module technologies. The project gathered actual operational data and analysed the monitored performance with the aim of understanding how technology, design and configuration affected the Levelised Cost of Energy (LCOE) for each technology and configuration. The study was conducted on a 400 kW research PV plant at the Eskom Research and Innovation Centre (ERIC) located in Rosherville, South Africa. The plant was designed to test the performance and efficiency of crystalline and thin film PV modules in different array configurations. The various performance parameters and final energy values being monitored show a lower than expected performance in terms of energy produced. This has a large impact on the expected final LCOE of the various arrays and illustrates the importance of optimising and maintaining plant performance.

description: Rare $d$-electron derived heavy-fermion properties of the solid-solution series LaCu$_3$Ru$_x$Ti$_{4-x}$O$_{12}$ were studied for $1 \leq x \leq 4$ by resistivity, susceptibility, specific-heat measurements, and magnetic-resonance techniques. The pure ruthenate ($x = 4$) is a heavy-fermion metal characterized by a resistivity proportional to $T^2$ at low temperatures $T$. The coherent Kondo lattice formed by the localized Ru 4$d$ electrons is screened by the conduction electrons leading to strongly enhanced effective electron masses. By increasing titanium substitution the Kondo lattice becomes diluted resulting in single-ion Kondo properties like in the paradigm $4f$-based heavy-fermion compound Ce$_x$La$_{1-x}$Cu$_{2.05}$Si$_2$ [M. Ocko {\em et al.}, Phys. Rev. B \textbf{64}, 195106 (2001)]. In LaCu$_3$Ru$_x$Ti$_{4-x}$O$_{12}$ the heavy-fermion behavior finally breaks down on crossing the metal-to-insulator transition close to $x = 2$.

description: High-power diesel-based or grid-connected irrigation systems are giving way to high-power photovoltaic irrigation systems (PVIS) without batteries that reduce the energy costs by up to 80%. The operation of PVIS is affected by factors other than their quality, and there are no experimental data available about their performance. The traditional performance ratio (PR) needs to be factorized to better understand the losses strictly related with the PV system itself, the ones that vary with the crop and its irrigation period, what is intrinsic to the PVIS design, and what happens as a consequence of the behavior of the end-user. This article provides the PV community experimental performance data of a battery-free 160 kWp PV-powered constant pressure center-pivot irrigation system. The system has been analyzed over one year of real operation in which the performance ratio was 48.1%.

description: The coupled kinetic equation for density and spin Wigner functions are derived including spin-orbit coupling, electric and magnetic field as well as selfconsistent Hartree meanfields suited for SU(2) transport. The interactions are assumed to be with scalar and magnetic impurities as well as scalar and spin-flip potentials among the particles. The spin-orbit interaction is used in a form suitable to solid state physics with Rashba or Dresselhaus coupling, graphene, extrinsic spin-orbit coupling as well as effective nuclear matter coupling. The deficiencies of the two-fluid model are worked out consisting in the appearance of an effective in-medium spin-precession. The stationary solution of all these systems shows a band splitting controlled by an effective medium-dependent Zeeman field. The selfconsistent precession direction is discussed and a cancellation of linear spin-orbit coupling at zero temperature is reported. The precession of spin around this effective direction caused by spin-orbit coupling leads to anomalous charge and spin currents in an electric field. Anomalous Hall conductivity is shown to consists of the known results obtained from Kubo formula or Berry phases and a new symmetric part interpreted as inverse Hall effect. Analogously the spin-Hall and inverse spin-Hall effect of spin currents are discussed which are present even without magnetic fields showing a spin accumulation triggered by currents. The analytical dynamical expressions for zero temperature are derived and discussed in dependence on the magnetic field and effective magnetizations. The anomalous Hall and spin-Hall effect changes sign at higher than a critical frequency dependent on the relaxation time.

description: In rural electrification and off-grid areas a new concept of providing energy access arises: Swarm electrification. The concept is based on energy sharing between individual solar homes systems (SHS). The aim of this study is to analyze how different designs of SHS and different azimuth & tilt angles of PV panels influence the energy sharing with the goal of enabling swarm electrification. The paper both looks at this effect for a case close to the equator and a different case in the northern hemisphere. The two case studies are from Kenya and from Norway. Different types of sharing scenarios were analyzed for two households in each case study. The findings show that the benefit of energy sharing highly depends on the sharing scenarios. Sharing only surplus energy showed very little potential of improvement. Sharing both surplus energy and battery capacity can improve the household with the initially smaller installed PV capacity but decreases the served load ratio for the household with the initially higher PV capacity. The results show that a deviation from the PV azimuth angle with maximum yield, to get a more diverse PV generation (i.e., all panels South oriented vs East or West), show no significant benefits in the sharing scenarios in the simulated cases.

description: This article investigates, using a sociology of profession approach, why veterinarians and aqua medicine biologists share jurisdiction in fish health in Norway. I use a five- actor framework to highlight key events in the development of the Norwegian model for inter-professional and cross-sectoral collaboration in fish health. Veterinarians were initially the only profession involved in fish health. However, in the late 1980s, the Norwegian aquaculture industry suffered great losses due to significant disease out- breaks. Lack of scientific knowledge about the disease causing the outbreaks, Hitra disease, and lack of veterinary capacity to cope with the problem resulted in a situation in which veterinarians continued, as an early response to the disease, to use antibiotic- based therapies. The marine science milieu, with support from the aquaculture industry, instituted a vaccine solution to the endemic Hitra disease in 1987. This scientific breakthrough had major impacts on combatting fish diseases and on the further development of vaccines. New vaccine solutions for other diseases, such as furuncu- losis, were developed by international and multidisciplinary collaboration. Over a 7- year period, the use of antibiotic-based therapy was dramatically reduced. The control of fish diseases is aquaculture’s X factor, and without these vaccine solutions and regulation regimes, the story of Norwegian aquaculture could have been different. The successful development of the Hitra disease vaccine enabled the marine science milieu at the University of Bergen and the University of Tromsø to establish a new programme of education for aqua medicine biologists based on their own scientific knowledge base. However, their struggle for shared jurisdiction, including the right to prescribe veterinary medicine, lasted nearly 20 years. In 2005, veterinary legislation was amended, and in addition to medical doctors, dentists and veterinarians, aqua medicine biologists, as the fourth profession in Norway, gained the right to prescribe medical products. I argue that the experience in Norway, where professionals from two different sectors share jurisdiction and work side by side in fish health, is worth examining as a model for organizing inter-professional and cross-sectoral collaboration.
A Theory of Everything: A Self-Similar Anthropomorphic Universe
Creators: name: Madocks, John
Publisher: name: Zenodo

description: This paper presents a Theory of Everything (TOE). This theory aims to be a true TOE, one that accounts for all verified physical and human phenomenon. This theory shows our universe to be composed of several self-similar copies at scales descending in a logarithmic spiral sequence. As different as it is, this TOE is actually a grand simplification over current theories. Rather than different laws of physics applying to the atomic, human and cosmic scales, this TOE shows one set of laws applies to all scales. In doing this, incongruities between quantum physics and gravity are resolved and open fundamental questions are answered. For instance, this TOE successfully explains the flat rotation profiles of spiral galaxies and the fine structure constant.

description: In this paper, two-dimensional (2-D) hybrid simulations are performed to investigate ion dynamics at a rippled quasi-parallel shock. The results show that the ripples around the shock front are inherent structures of a quasi-parallel shock, and the reformation of the shock is not synchronous along the surface of the shock front. By following the trajectories of the upstream ions, we find that these ions behave differently when they interact with the shock front at different positions along the shock surface. The upstream particles are easier to transmit through the upper part of a ripple, and the bulk velocity in the corresponding downstream is larger, where a high-speed jet is formed. In the lower part of the ripple, the upstream particles tend to be reflected by the shock. For the reflected ions by the shock, they may suffer multiple stage acceleration when moving along the shock surface, or trapped between the upstream waves and the shock front. At last, these ions may escape to the further upstream or enter the downstream, therefore, the superthermal ions can be found in both the upstream and downstream.

description: With the aim of a more balanced production pattern PV systems are installed in increasing number with in a “delta” configuration with module facing east and west with a certain inclination angle to the horizontal. The production patten of these systems should show a less “peaked” appearance around noon and improved generation in the morning and evening hours as compared to systems with south facing modules with the costs of a reduced overall energy gain. As both, the positive effect of a more balanced production and the reduced overall gain are expected to depend on location (by location specific incidence angles) and clearness index (by various mix of diffuse and direct irradiance additionally modifying the effective irradiance) the respective is expected to show a site dependence.

description: The Supersymmetric Custodial Triplet Model, a supersymmetric generalization of the Georgi-Machacek model, has proven to be an interesting modification of the MSSM. It extends the MSSM Higgs sector by three extra SU(2)L triplets in such a way that approximate custodial invariance is preserved and rho-parameter deviations are kept under control. By means of a sizeable triplet contribution to electroweak breaking the model is able to generate a barrier at tree level between the false vacuum and the electroweak one. This will result in a strong first order phase transition for an important region of the parameter space. We also look at the gravitational waves that could be generated as a result of the phase transition and show how future interferometers could be used as a probe of the model.

description: The main objective of this study is to examine the effect of ERP implementation on the internal supply chain performance of ethio telecom with respect to ERP implementation factors of project plan & vision, top management support, project management, project champion, user training, IT infrastructure, Vendor support and communication. Both quantitative and qualitative research approaches were used in the study. Explanatory research design was used to identify ERP implementation factors and to examine the effect of ERP implementation on the internal supply chain performance of the case company. Simple random sampling was used to select the appropriate samples of the study. All of the implementation factors were found to have positive and significant correlation with the dependent variable which is internal supply chain performance. The ANOVA test result showed that, the value of R and R 2 obtained under the model summary was statistically significant. The multiple linear regression analysis revealed that, 6 of the 8 independent variables (top management support, project management, user training, IT infrastructure, vendor support and communication) have a statistically significant relationship to predict internal supply chain performance. The other 2 variables (project plan & vision and project champion) are not statistically significant to predict internal supply chain performance. User training and IT infrastructure accounts the largest share to explain the variation of internal supply chain performance. Key Words: User training, vendor support, communication, top management support, IT infrastructure, project management, project champion, project plan & vision

description: Extensive increases in electricity demand plus numerous power outages encountered in developing countries has led to the deployment of costly, polluting, and unreliable diesel generators to ensure continuity of power. This paper proposes a robust grid-interactive hybrid (PV/Battery-Storage/Diesel-Genset) power system for a site in Lwak, Kenya, the primary objective being the minimization of generator usage and grid cost, and also increasing reliability of supply. To model the entire system, a commercial software, HOMER Pro Version 3.14 is used to evaluate the performance of each component and perform sensitivity analysis to optimize the system. Based on measured load demand, energy potentials, and the related cost, various design configurations are assessed, and the optimal design is selected. The proposed system is selected to most optimally supply the demand with minimal Net Present Cost (NPC), Levelised Cost of Energy (LCOE), emissions, and generator fuel consumption. Demand Side Management (DSM) is also modelled to demonstrate how peak load and storage requirements can be reduced by maximizing usage of the solar production and utilizing excess energy immediately. The designed microgrid systems with individual connections to the main grid will later be interconnected to each other to form resilient and stable interactive power systems.
