description: Emerging applications in Internet of Things (IoT) and Cyber-Physical Systems (CPS) present novel challenges to Big Data platforms for performing online analytics. Ubiquitous sensors from IoT deployments are able to generate data streams at high velocity, that include information from a variety of domains, and accumulate to large volumes on disk. Complex Event Processing (CEP) is recognized as an important real-time computing paradigm for analyzing continuous data streams. However, existing work on CEP is largely limited to relational query processing, exposing two distinctive gaps for query specification and execution: (1) infusing the relational query model with higher level knowledge semantics, and (2) seamless query evaluation across temporal spaces that span past, present and future events. These allow accessible analytics over data streams having properties from different disciplines, and help span the velocity (real-time) and volume (persistent) dimensions. In this article, we introduce a Knowledge-infused CEP (X-CEP) framework that provides domain-aware knowledge query constructs along with temporal operators that allow end-to-end queries to span across real-time and persistent streams. We translate this query model to efficient query execution over online and offline data streams, proposing several optimizations to mitigate the overheads introduced by evaluating semantic predicates and in accessing high-volume historic data streams. The proposed X-CEP query model and execution approaches are implemented in our prototype semantic CEP engine, SCEPter. We validate our query model using domain-aware CEP queries from a real-world Smart Power Grid application, and experimentally analyze the benefits of our optimizations for executing these queries, using event streams from a campus-microgrid IoT deployment.

description: Despite recognition that agency matters for teachers’ effective performance, psychological theories underlying agency have not been clearly established to date. This thesis addresses the deficit in understanding teachers’ choices to act by examining potential constructs related to agency. The thesis begins by reviewing existing theories of agency, motivation and emotions, and highlighting issues with existing research. Next, four studies are described. The first involved thematic analysis of interviews with thirteen teachers in Scottish schools about their experience of teaching during the Covid-19 pandemic. The second study surveyed 500 teachers using standardised questionnaires related to emotion, self-efficacy and agency, and resulting data were analysed using structural equation modelling and latent profile analysis. The third study involved interviewing seven teachers over four months to consider the impact of awareness of emotion on their beliefs and actions. The fourth study involved reflection on the author’s experiences as a student, teacher and researcher, examining relationships between emotional experiences, beliefs and actions. Emerging findings included that: (i) the emotional percepts of CARE, CURIOSITY, COOPERATION and CHALLENGE individually and collectively influenced teachers’ beliefs about their efficacy and choices available to them to act; (ii) deliberate inaction and collective action are forms of agency; (iii) individual differences in levels and patterns of emotional percepts reflect self-efficacy and agency levels; (iv) modes of agency differ depending on teachers’ beliefs about choices available for action; and (v) awareness of percepts facilitates reflection, leading to cognitive and behavioural change, notably improved self-care. Theory is advanced by identifying the role of emotional percepts as a route to, or driver of, teacher agency, proposing awareness of emotional experience as an effective route to action. Findings offer the potential to improve teachers’ agency as continuing changes in circumstances affect them and their students. Future studies should examine practical benefits of the theory for teachers and students.

description: MAXCUT defines a classical NP-hard problem for graph partitioning and it serves as a typical case of the symmetric non-monotone Unconstrained Submodular Maximization (USM) problem. Applications of MAXCUT are abundant in machine learning, computer vision and statistical physics. Greedy algorithms to approximately solve MAXCUT rely on greedy vertex labelling or on an edge contraction strategy. These algorithms have been studied by measuring their approximation ratios in the worst case setting but very little is known to characterize their robustness to noise contaminations of the input data in the average case. Adapting the framework of Approximation Set Coding, we present a method to exactly measure the cardinality of the algorithmic approximation sets of five greedy MAXCUT algorithms. Their information contents are explored for graph instances generated by two different noise models: the edge reversal model and Gaussian edge weights model. The results provide insights into the robustness of different greedy heuristics and techniques for MAXCUT, which can be used for algorithm design of general USM problems.

Publisher: name: African Journal of Leadership and Development
Year: 2019

description: Job satisfaction is vital to maintain and retain employees within the organization and reduce the expense of hiring new employees; Even with the authority hiring new graduates from different universities, turnover is increasing from year to year. The challenge is indeed severe, instigated by poor motivation and resulting in job dissatisfaction (ERCA, 2016). The research design was descriptive, and the research was conducted by using both primary and secondary data. The sampling technique used was stratified sampling. Simple random sampling method was employed after the employees were stratified by educational level. The sample size was 271 selected from the total employee population. The study found that employees of ERCA are not satisfied with their jobs due to the absence of growth and development opportunities, job insecurity, poor working conditions, and lack of recognition programs. Moreover, the promotional policies are not known by the employees, and staff members are not promoted on merit or based on their experience and/or performance. Finally, the study recommends that compensation and incentive packages be developed and implemented properly. Well organized career structure opportunities should be put in place. Supervisors should empower officers and even require them to make decisions independently. Managers/Supervisors/Team Leaders should evaluate based on performance and develop recognition programs to encourage best performance.

title: Legal treatment of foreign direct investment in Egypt : a study on investment climate in developing countries
Creators: name: Hammoud, Salim Ahmed
Publisher: name: University of Kent
Year: 2023

description: In recent years, attitudes and policies of developing countries towards foreign direct investment have witnessed a clear change from suspicion to openness and competition. Nowadays, ideological differences between developed, developing countries are decreasing, and developing countries are moving from blocking the inflow of FDI into the mode, which welcome and promote FDI in their territory. It is recognised that the best way to achieve thus is through working on creating a sound investment climate. For developing countries, such as Egypt, Foreign direct investment is a vital package of capital, technology, management skills, and expertise. Therefore, FDI is very important as it helps to strengthen the balance of payment of developing countries through the flow of foreign capital and through the generation of foreign exchange earnings in the long run. As a result, all states working for increasing the inflow of FDI tend to relax restrictions and to offer great inducements in order to create a favourable investment climate. The efforts have paid off in Egypt, but not enough. An investment climate consists of three main factors: political, economic, and legal. The first two factors are clearly well covered by many article and books. The legal literature is still far behind. Much of the available legal literature is not comprehensive and focuses on some issues such as the BITs and others. The purpose of this thesis is to examine the legislative framework governing foreign direct investment in Egypt. M ore specifically, it focuses on the regulatory control exerted over foreign entities in order to judge the success of the investment climate in attracting the required FDI During Egypt's transition era from a centrally planned of a market-oriented economy, national legislation designed to attract foreign capital needed to be reformed and developed. Simultaneously, it had also to allow the authorities to effectively screen the entry of foreign investment and supervise the operations of foreign enterprises. The various control mechanisms in Egypt remains far from those required. This does not create an impediment to a greater inflow of FDI, but also account for an insufficient investment environment. Amidst efforts to reconcile the tenets of a market economy with socialist ideology, the handling of foreign interest in Egypt remains highly conditioned by various ideological, political, historical, and cultural factors. The objective of this study is to illuminate the current legal standards on the investment climate in developing countries. This study will be valuable as a source of information on issues affecting the investment climate in host states.

description: We investigate the spontaneous emission rate of a two-level quantum emitter next to a composite medium made of randomly distributed metallic inclusions embedded in a dielectric host matrix. In the near-field, the Purcell factor can be enhanced by two-orders of magnitude relative to the case of an homogeneous metallic medium, and reaches its maximum precisely at the insulator-metal transition. By unveiling the role of the decay pathways on the emitter's lifetime, we demonstrate that, close to the percolation threshold, the radiation emission process is dictated by electromagnetic absorption in the heterogeneous medium. We show that our findings are robust against change in material properties, shape of inclusions, and apply for different effective medium theories as well as for a wide range of transition frequencies.

description: The Cesaro operator $\mathsf{C}$, when acting in the classical growth Banach spaces $A^{-γ}$ and $A_0^{-γ}$, for $γ> 0 $, of analytic functions on $\mathbb{D}$, is investigated. Based on a detailed knowledge of their spectra (due to A. Aleman and A.-M. Persson) we are able to determine the norms of these operators precisely. It is then possible to characterize the mean ergodic and related properties of $\mathsf{C}$ acting in these spaces. In addition, we determine the largest Banach space of analytic functions on $\mathbb{D}$ which $\mathsf{C}$ maps into $A^{-γ}$ (resp. into $A_0^{-γ}$); this optimal domain space always contains $A^{-γ}$ (resp. $A_0^{-γ}$) as a proper subspace.

description: We introduce a cohomology theory for spatial super- product systems and compute the $2-$cocycles for some basic examples called as Clifford super-product systems, thereby distinguish them up to isomorphism. This consequently proves that a family of $E_0-$semigroups on type III factors, which we call as CAR flows, are non-cocycle-conjugate for different ranks. Similar results follows for the even CAR flows as well. We also compute the automorphsim group of the Clifford super-product systems.

description: First-principles molecular dynamics (FPMD) simulations are performed on 6 and 12% Na in dense liquid N. A detailed description of structural and electronic properties leading to an understanding of the effect of Na-doping on the polymerization phase transition of N is presented. Compression of the mixtures from 5 to 90 GPa shows three distinct regions of characteristic local order separated by pressures near 30 and 65 GPa. Computation of Gibbs free energies of mixing shows that these mixtures are thermodynamically stable beyond 20 and 15 GPa for 6 and 12 % Na respectively.

description: In this study we investigate the effect of congruency between the reading direction (i.e., from left to right) and the direction of depicted motion (either to right or to left) in the context of the reading of comic-book-style strips. We measure reaction times and accuracy of motion direction. We expect that the incongruency between the reading direction and the direction of depicted motion would lead to longer reaction times and worse accuracy than when they are congruent.

description: We show that closed aspherical manifolds supporting an affine structure, whose holonomy map is injective and contains a pure translation, must have vanishing simplicial volume. This provides some further evidence for the veracity of the Auslander Conjecture. Along the way, we provide a simple cohomological criterion for aspherical manifolds with normal amenable subgroups of $π_1$ to have vanishing simplicial volume. This answers a special case of a question due to Lück.

Assessment of Customer Satisfaction on Public Employees Transport Service Delivery: The Case of Public Service Employees’ Transport Service Enterprise (PSETSE)
Creators: name: Mekonnen, Sofoniyas
Publisher: name: African Journal of Leadership and Development
Year: 2019

description: Public enterprises are organizations established and owned by government to provide different services to the public. Most of the time these enterprises give their services to the public by collecting fees that are less than the market price of the goods and services provided. Basically, the government subsidizes the goods and services. Their customers are important stakeholders in organizations and their satisfaction is a priority to management. Most of these enterprises apply different types of activities to improve their service provision capacity to enhance the customers’ satisfaction. Currently, Public Service Employees Transport Service Enterprise (PSETSE) implemented different activities to improve its service delivery and maximize their customers’ satisfaction. This study was conducted to assess the service delivery performance and level of the customers’ satisfaction of PSETSE. To achieve the objectives of this study, data was collected through questionnaires from a sample of 605 north direction customers of the Enterprise. The respondents were selected using simple random sampling method. Additional data was collected through interview with the transport service core process manger of the Enterprise. The data were analyzed using statistical tools such as percentage and frequency analysis. Service delivery of the Enterprise was evaluated by using the four factors namely, safety, comfort, performance and reliability, driver’s behavior and condition of the vehicle and facilities. The results indicate that, almost all factors used to measure the service delivery of Enterprise rated as good and customers are satisfied except some factors within the dimensions. Generally, the finding of this study indicates that customers were satisfied by overall service provision of the Enterprise. Based on the findings of the study, the researcher forwards some recommendations like increasing the number of buses in the crowded routes, supporting service delivery with IT support, modify the design of the buses by considering disabled passengers and pregnant women, and others which help to improve the Enterprise service delivery performance.

description: We report the discovery of infalling motion with rotation of S235AB the massive cluster-forming clump (~10^3 Mo) in the S235 region. Our C18O observations with the 45m telescope at the Nobeyama Radio Observatory have revealed the elliptical shape of the clump. Position-velocity (PV) diagram taken along its major axis exhibits two well-defined peaks symmetrically located with respect to the clump center, which is similar to that found for a dynamically infalling envelope with rotation around a single protostar modeled by N. Ohashi and his collaborators, indicating that the cluster-forming clump is also collapsing by the self-gravity toward the clump center. With analogue to Ohashi's model, we made a simple model of an infalling, rotating clump to fit the observed data. Based on the inferred model parameters as well as results of earlier observations and simulations in the literature, we discuss structures of the clump such as the relation among the global mass infall rate (~10^-3 Mo/yr), formation of a compact core (with a mass and size of ~4 Mo and < 0.1 pc) at the center, and a massive star (~11 Mo) forming in the core.

Constrained Phase Noise Estimation in OFDM Using Scattered Pilots Without Decision Feedback

description: In this paper, we consider an OFDM radio link corrupted by oscillator phase noise in the receiver, namely the problem of estimating and compensating for the impairment. To lessen the computational burden and delay incurred onto the receiver, we estimate phase noise using only scattered pilot subcarriers, i.e., no tentative symbol decisions are used in obtaining and improving the phase noise estimate. In particular, the phase noise estimation problem is posed as an unconstrained optimization problem whose minimizer suffers from the so-called amplitude and phase estimation error. These errors arise due to receiver noise, estimation from limited scattered pilot subcarriers and estimation using a dimensionality reduction model. It is empirically shown that, at high signal-to-noise-ratios, the phase estimation error is small. To reduce the amplitude estimation error, we restrict the minimizer to be drawn from the so-called phase noise geometry set when minimizing the cost function. The resulting optimization problem is a non-convex program. However, using the S-procedure for quadratic equalities, we show that the optimal solution can be obtained by solving the convex dual problem. We also consider a less complex heuristic scheme that achieves the same objective of restricting the minimizer to the phase noise geometry set. Through simulations, we demonstrate improved coded bit-error-rate and phase noise estimation error performance when enforcing the phase noise geometry. For example, at high signal-to-noise-ratios, the probability density function of the phase noise estimation error exhibits thinner tails which results in lower bit-error-rate.

description: This report is a brief evaluation of a pilot walking project for Syrian families in Greenwich. Syrian refugee communities are at high risk of social exclusion, poor health and mental illness due to the traumatic experiences leading to their resettlement, separation from friends and family, income poverty, loss of identity and feeling separate from their new communities. Many of the families identify as feeling isolated, and loneliness has been described as the biggest challenge facing refugee communities in London. This was an innovative pilot project to support Syrian families to participate in walks with their children with the objectives to improve social inclusion and well-being. Though a small project, the evidence that these four walks had a positive impact for the families is strong. 30 Syrians from 12 different families participated in at least one walk, and some participated in all of the walks.The families learnt new English words, visited new places, had the opportunity for exercise, socialised, shared food and enjoyed nature. Considering that some of the families explained that they never left the house, these opportunities were extremely valuable. Looking to the future, there walks provided the space for much needed learning to support similar projects to engage marginalised communities in connecting with outdoor spaces, group walks and their related benefits in the future.

description: Collective excitation modes in solid state systems play a central role in circuit quantum electrodynamics, cavity optomechanics, and quantum magnonics. In the latter, quanta of collective excitation modes in a ferromagnet, called magnons, interact with qubits to provide the nonlinearity necessary to access quantum phenomena in magnonics. A key ingredient for future quantum magnonics systems is the ability to probe magnon states. Here we observe individual magnons in a millimeter-sized ferromagnet coherently coupled to a superconducting qubit. Specifically, we resolve magnon number states in spectroscopic measurements of a transmon qubit with the hybrid system in the strong dispersive regime. This enables us to detect a change in the magnetic dipole of the ferromagnet equivalent to a single spin flipped among more than $10^{19}$ spins. The strong dispersive regime of quantum magnonics opens up the possibility of encoding superconducting qubits into non-classical magnon states, potentially providing a coherent interface between a superconducting quantum processor and optical photons.

description: The exponential growth of scientific data has led to an increasing demand for effective data management and storage solutions. Academic computing infrastructures are often fragmented, which can make it challenging for researchers to leverage cloud-native principles and modern data analysis tools. To address this challenge, a new distributed storage platform called Aruna Object Storage (AOS) was developed. AOS is a cloud-native, scalable, and domain-agnostic object storage system that provides an S3-compatible interface for a variety of data analysis tools like Apache Spark, TensorFlow, and Pandas. The system uses an underlying distributed NewSQL database to manage detailed information about its resources and can be deployed across multiple data centers for geo-redundancy. AOS is designed to support modern DataOps practices, including the adoption of FAIR principles. Resources in AOS are organized into Objects, Datasets, Collections and Projects, which represent relations of data objects. Additionally, these can be further annotated with key-value pairs called Labels and Hooks to provide additional information about the data. The system's event-driven architecture makes it easy to automate actions and enforce data validation checks, significantly improving accessibility and reproducibility of scientific results. AOS is open source and freely available via https://aruna-storage.org.

description: Inference methods are often formulated as variational approximations: these approximations allow easy evaluation of statistics by marginalization or linear response, but these estimates can be inconsistent. We show that by introducing constraints on covariance, one can ensure consistency of linear response with the variational parameters, and in so doing inference of marginal probability distributions is improved. For the Bethe approximation and its generalizations, improvements are achieved with simple choices of the constraints. The approximations are presented as variational frameworks; iterative procedures related to message passing are provided for finding the minima.

description: This paper focuses on inhomogeneous quadratic tests, which involve the sum of a dependent non-central chi-square with a Gaussian random variable. Unfortunately, no closed-form expression is available for the statistical distribution of the resulting random variable, thus hindering the analytical characterization of these tests in terms of probability of detection and probability of false alarm. In order to circumvent this limitation, two closed-form approximations are proposed in this work based on results from Edgeworth series expansions and Extreme Value Theory (EVT). The use of these approximations is shown through a specific case of study in the context of integrity transient detection for Global Navigation Satellite Systems (GNSS). Numerical results are provided to assess the goodness of the proposed approximations, and to highlight their interest in real life applications.

description: The major purpose of the study was to assess the current practices, challenges and prospects of social security management in public servants’ social security agency in Addis Ababa. To this end, the study adopts a mixed methods research approach by combining questionnaire, focus group discussion and in-depth interviews. Both proportionate stratified random sampling and purposive sampling methods were used in this study to obtain data from employees and top management respectively. A sample of 230 out of 539 employees of the agency and 3 top management officials were drawn. The findings of the study show that, there is lack of promoting saving, lack of awareness creation programs to employees, poor measurement of actual performance with the desired goals, financial sustainability of the agency is at risk, extension of social security coverage is still less, lack of proper implementation of the strategic plan, low continues supervision and follow-up system and the application of the management functions of the agency is very low. The study suggests that the agency should design device mechanisms for financial sustainability and governance of social security, integrate social security into a comprehensive strategy for decent work and strictly follow and apply the management functions.

description: Since the outbreak of COVID-19 few years ago, the increasing of the number of medical waste has become a huge issue because of their harmful impact to environment. A major concern associated to the limitation of technologies for dealing with medical waste, especially conventional technologies, are overcapacities since pandemic occurs. Moreover, the outbreak of new viruses from post COVID-19 should become a serious attention to be prevented not only environmental issues but also the spreading of viruses to new pandemic near the future. The high possibility of an outbreak of new viruses and mutation near the future should be prevented based on the experience associated with the SARS-CoV-2 virus in the last 3 yr. This review presented information and strategies for handling medical waste during the outbreak of COVID-19 and post-COVID-19, and also information on the current issues related to technologies, such as incineration, pyrolysis/gasification, autoclaves and microwave treatment for the dealing with high numbers of medical waste in COVID-19 to prevent the transmission of SARS-CoV-2 virus, their advantages and disadvantages. Plasma technology can be considered to be implemented as an alternative technology to deal with medical waste since incinerator is usually over capacities during the pandemic situation. Proper treatment of specific medical waste in pandemics, namely face masks, vaccine vials, syringes, and dead bodies, are necessary because those medical wastes are mediums for transmission of the SARS-CoV-2 virus. Furthermore, emission controls from incinerator and plasma are necessary to be implemented to reduce the high concentration of CO2, NOx, and VOCs during the treatment. Finally, future strategies of medical waste treatment in the perspective of potential outbreak pandemic from new mutation viruses are discussed in this review paper. Implications: Journal of the air and waste management association may consider our review paper to be published. In this review, we give important information related to the technologies, managements and strategies for handling the medical waste and control the transmission of SARS-CoV-2 virus, starting from proper technology to control the high number of medical waste, their pollutants and many strategies for controlling the spreading of SARS-CoV-2 virus. Moreover, this review also describes some strategies associated with control the transmission not only the SARS-CoV-2 virus but also the outbreak of new viruses near the future.

description: We investigated the impact of wildfires on maximum daily 8-hr average ozone concentrations (MDA8 O3) at four sites in Salt Lake City (SLC), Utah for May to September for 2006–2022. Smoke days, which were identified by a combination of overhead satellite smoke detection and surface PM2.5 data and accounted for approximately 9% of the total number of days, exhibited O3 levels 6.8 to 8.9 ppb higher than no-smoke days and were predominantly characterized by high daily maximum temperatures and low relative humidity. A Generalized Additive Model (GAM) was developed to quantify the impact of wildfire contributions to O3. The GAM, which provides smooth functions that make the interpretation of relationships more intuitive, employed 17 predictors and demonstrated reliable performance in various evaluation metrics. The mean of the residuals for all sites was approximately zero for the training and cross-validation data and 5.1 ppb for smoke days. We developed three approaches to estimate the contribution of smoke to O3 from the model residuals. These generate a minimum and maximum contribution for each smoke day. The average of the minimum and maximum wildfire contributions to O3 for the SLC sites was 5.1 and 8.5 ppb, respectively. Between 2006 and 2022, an increasing trend in the wildfire contributions to O3 was observed in SLC. Moreover, trends of the fourth-highest MDA8 O3 before and after removing the wildfire contributions to O3 at the SLC Hawthorne site in 2006–2022 were quite different. Whereas the unadjusted data do not meet the current O3 standard, after removing the contributions from wildfires the SLC region is close to achieving levels that are consistent with meeting the O3 standard. We also found that the wildfire contribution during smoke days was particularly high under conditions of high temperature, high PM2.5 concentration, and low cloud fraction. Implications: In this study, we quantified the impact of wildfires on maximum daily 8-hr average ozone concentrations (MDA8 O3) in Salt Lake City, Utah, using a Generalized Additive Model (GAM). The GAM results demonstrate the importance of wildfires as contributors to O3 air pollution. Our results suggest that states could use the GAM approach to assist in quantifying the wildfire contribution to MDA8 O3 under the U.S. EPA exceptional events rule. These findings also highlight the need for strategies to manage wildfires and their subsequent impacts on air quality in an era of climate warming.

description: Mean-field equations have been developed recently to approximate the dynamics of the Deffuant model of opinion formation. These equations can describe both fully mixed populations and the case where individuals interact only along edges of a network. In each case, interactions only occur between individuals whose opinions differ by less than a given parameter, called the confidence bound. The size of the confidence bound parameter is known to strongly affect both the dynamics and the number and location of opinion clusters. In this work, we carry out a mathematical analysis of the mean-field equations to investigate the role of the confidence bound and boundaries on these important observables of the model. We consider the limit in which the confidence bound interval is small, and we identify the key mechanisms driving opinion evolution. We show that linear stability analysis can predict the number and location of opinion clusters. Comparison with numerical simulations of the model illustrates that the early-time dynamics and the final cluster locations can be accurately approximated for networks composed of two degree classes, as well as for the case of a fully mixed population.
title: Polaris-SMC in-situ microwave reactor: a new technique for real time neutron diffraction of rapid microwave-induced syntheses

description: Direct microwave heating holds much promise in revolutionising the synthesis of solid state materials due to the clear benefits from greatly reduced reaction times and lower energy requirements compared to conventional methods. For the modern laboratory the principles of green chemistry to reduce energy usage and actions with a detrimental impact to the environment are increasingly taking prominence, and microwave reactors work well within this framework. The rapidity of microwave heating however, makes following a reaction progression and identification of unusual synthesis pathways a difficult process. The bespoke single mode cavity reactor designed to operate within the Polaris neutron diffractometer allows for neutron data to be collected over the short time scale of a microwave reaction. The neutron data is recorded with respect to time which can then be split into smaller sections to investigate the reaction pathways in increasingly granular detail. Throughout this project, several binary metal chalcogenide chemical systems known to be thermoelectric materials of interest were investigated. Thermoelectric generators make use of the Seebeck effect to generate useable currents from an applied temperature gradient, allowing waste heat to be converted back into valuable electricity. For each system a range of samples were prepared in which the selenium component was partially substituted with a either tellurium or sulfur in order to hopefully tune the thermoelectric properties. The substitution subprojects enabled a large list of samples to be prepared for synthesis in the Polaris-SMC microwave reactor under well understood reaction conditions. Many of these materials have not been produced previously using a direct microwave heating method in the solid state, and so the insights gained from the in-situ neutron data should help optimisation their synthesis conditions in the future.

description: In many navigational domains the traversability of cells is conditioned on the path taken. This is often the case in video-games, in which a character may need to acquire a certain object (i.e., a key or a flying suit) to be able to traverse specific locations (e.g., doors or high walls). In order for non-player characters to handle such scenarios we present invJPS, an "inventory-driven" pathfinding approach based on the highly successful grid-based Jump-Point-Search (JPS) algorithm. We show, formally and experimentally, that the invJPS preserves JPS's optimality guarantees and its symmetry breaking advantages in inventory-based variants of game maps.

description: This deliverable contains a detailed description of protocols and metadata schemes which are relevant for the NFDI4Earth. Protocols provide technological interoperability between Earth System Science (ESS) research data infrastructures, and common metadata schemes and vocabularies add semantic interoperability on top. The goal of this deliverable is on the one hand to provide a compact overview of these resource information types; compact information which afterwards shall be represented in the NFDI4Earth Knowledge Hub (KH). On the other hand, the deliverable describes how interoperability between the KH itself and ESS infrastructures can be reached by using established protocols for metadata harvesting and ensuring that the metadata schema of the KH is compatible with widely used vocabularies and schemas.
