"FoodChain-Lab Web: An integrative modular software to visualise and analyse complex global food supply chain networks during foodborne incidents." ARPHA Conference Abstracts 4 (May 28, 2021): e68835. https://doi.org/10.3897/aca.4.e68835.
Full textAbstract:
In times of globalised food and feed trade, powerful integrative software tools are essential to solve foodborne crises quickly and reliably. The FoodChain-Lab web application (FCL Web; https://fcl-portal.bfr.berlin/) is such a tool. FCL Web is free and open-source software which helps to trace back and forward food along complex global supply chains during foodborne disease outbreaks or other food-related events. In the framework of One Health EJP COHESIVE, the efforts of several national and international tracing-related software projects are integrated within FCL Web to provide a modular tracing platform following the One Health approach.FCL Web unifies interactive tracing data visualisation, analysis as well as reporting - and in the future data collection - in one modular tracing platform (Fig. 1). The interactive analysis module was developed in a project with EFSA and offers automated visualisation of supply chains based on the needs of the user. A data table displays key information on involved food business operators and food items and includes comprehensive filter functions to analyse the information given in the table. The analysis module also helps to run simulations on hypothetical cross contamination or geographic clustering events during outbreaks via a scoring algorithm for deliveries and food business operators. A pilot version of a reporting module was integrated in FCL Web as well to display tracing, sample and case information in a format suitable for publishing tracing results in outbreak reports. A web-based tracing data collection mask offering a guided and structured data assessment with access to curated data was developed in a national project and will be integrated in FCL Web soon. Its multi-language design allows for potential European-wide use. In the future, more modules, e.g. to analyse genome sequencing data in the context of tracing are planned for FCL Web.With its features and its integrative approach, FCL Web blends seamlessly into a list of crucial tracing tool projects in Europe. In the future, these tools will be strongly interconnected to serve several tracing purposes on the local, national or European level. Hence, there is a need to improve interoperability of the tools e.g. via a universal data exchange format.

Full textAbstract:
Glaucoma is a leading cause of blindness worldwide whose detection is based on multiple factors, including measuring the cup to disc ratio, retinal nerve fiber layer and visual field defects. Advances in image processing and machine learning have allowed the development of automated approached for segmenting objects from fundus images. However, to build a robust system, a reliable ground truth dataset is required for proper training and validation of the model. In this study, we investigate the level of agreement in properly detecting the retinal disc in fundus images using an online portal built for such purposes. Two Doctors of Optometry independently traced the discs for 159 fundus images obtained from publicly available datasets using a purpose-built online portal. Additionally, we studied the effectiveness of ellipse fitting in handling misalignments in tracing. We measured tracing precision, interobserver variability, and average boundary distance between the results provided by ophthalmologists, and optometrist tracing. We also studied whether ellipse fitting has a positive or negative impact on properly detecting disc boundaries. The overall agreement between the optometrists in terms of locating the disc region in these images was 0.87. However, we found that there was a fair agreement on the disc border with kappa = 0.21. Disagreements were mainly in fundus images obtained from glaucomatous patients. The resulting dataset was deemed to be an acceptable ground truth dataset for training a validation of models for automatic detection of objects in fundus images.

Full textAbstract:
In modern freeform surfaced optics manufacturing, ultraprecision machining through single-point diamond turning (SPDT) plays a crucial role due to its ability to meet the high accuracy demands of optical design and stringent surface quality requirements of the final optic. The process involves meticulous steps, including optic surface modeling and analysis, optic design, machining toolpath generation, and manufacturing. This paper presents an integrated approach to customized precision design and the manufacturing of freeform surfaced varifocal lenses through a web-based e-portal. The approach implements an e-portal-driven manufacturing system that seamlessly integrates lens design, modeling and analysis, toolpath generation for ultraprecision machining, mass personalized customization, and service delivery. The e-portal is specifically designed to meet the stringent demands of personalized mass customization, and to offer a highly interactive and transparent experience for the lens users. By using Shiny and R-script programming for platform development and combining COMSOL Multiphysics for the ray tracing simulation, the e-portal leverages open-source technologies to provide manufacturing service agility, responsiveness, and accessibility. Furthermore, the integration of R-script and Shiny programming allows for advanced interactive information processing, which also enables the e-portal-driven manufacturing system to be well suited for personalized complex products such as freeform surfaced lenses.

Full textAbstract:
Abstract Big data analytics (BDA) has the 5-v benefit of volume, variety, veracity, velocity, and value and has the potential to help adaptation to climate change. This paper reports the preconditions for designing the BDA system specifically for adapting to climate change, the designing of this BDA system, and the actual performance. In terms of layers, the components of the BDA system have five integrated layers: the persistent layer, the distributed data storage indexing layer, the web-based data analytics layer, the web-based layer responding to web-based requesting portals, and the web portal layers for specialist administrators to make responses. The BDA system includes the primary database, the sectoral database, and the integration process. The BDA generally met the preconditions and the goals of improving the adaptation capacity to climate change. The trial use of this BDA covered seven provinces in terms of geographic areas and covered preventing flood, tracing diseases caused by climate change, zoning and planning urban areas, and other fields in terms of content. The actual performance indicates that this BDA system functions well as to the speed of processing, the soundness of analysis, and the accuracy of data. However, there is still a need to improve its capacity to spot and detect erroneous but non-conflicting data.

Full textAbstract:
This paper presents an interactive online e-portal development and application using Shiny/R version 4.4.0 programming for personalised varifocal lens surface design and manufacturing in an agile and responsive manner. Varifocal lenses are specialised lenses that provide clear vision at both far and near distances. The user interface (UI) of the e-portal application creates an environment for customers to input their eye prescription data and geometric parameters to visualise the result of the designed freeform varifocal lens surface, which includes interactive 2D contour plots and 3D-rendered diagrams for both left and right eyes simultaneously. The e-portal provides a unified interactive platform where users can simultaneously access both the specialised Copilot demo web for lenses and the main Shiny/R version 4.4.0 programming app, ensuring seamless integration and an efficient process flow. Additionally, the data points of the 3D-designed surface are automatically saved. In order to check the performance of the designed varifocal lens before production, it is remodelled in the COMSOL Multiphysics 6.2 modelling and analysis environment. Ray tracing is built in the environment for the lens design assessment and is then integrated with the lens additive manufacturing (AM) using a Formlabs 3D printer (Digital Fabrication Center (DFC), London, UK). The results are then analysed to further validate the e-portal-driven personalised design and manufacturing approach.

Full textAbstract:
Web analytics are typically branded as a tool for measuring website traffic. They can be equally used as a tool for business research, results of advertising campaigns, and market research. Web analytics provide data on the number of visitors, page views, measure a visitor’s navigation through a website, etc. This collection of data is typically compared against some metrics to indicate whether the web site is delivering expected values, what improvements should be considered, and so on. These metrics are also used to improve a web site or marketing campaign’s audience response. Tracking portal visits are important in order to obtain a better understanding of which parts of the portal are delivering value. However, portals have unique attributes associated with the page composition techniques, page, and portlet refresh. Portal always presents multiple topics on the same page, which pose specific challenges to explore exciting opportunities allowing the web designer to gain insights about portal usage and user behaviour. Furthermore, portals are inherently multidimensional, and effective tools to monitor and analyse portal data usage must be able to support multidimensional analysis.

This article explores the following aspects: increase in the number of audits of small and medium-sized businesses; information awareness of small and medium-sized businesses about the reform of the means of control and supervision in the Russian Federation; availability of information on mandatory requirements. The year 2019 was transitional, and its results allowed assessing the effectiveness and forecasting the prospects of the reform of control and supervision activity. The scale of the ongoing reform is enormous. However, it remains relevant whether the small and medium-sized businesses are informed about such transformations The scientific novelty consists in tracing the interrelation between dissatisfaction among the representatives of small and medium-sized businesses with the implemented control and supervisory activity and their awareness of the reform in the Russian Federation, as well as the availability of information on mandatory requirements. The conclusion is made on the need to develop and implement the project aimed at informing small and medium-sized businesses about the implementation of the reform of the means of control and supervision in the Russian Federation, as well as the conditions for their operation within the framework of the reform. The author also offers to introduce the system of common register of mandatory requirements and guidelines for their observance in accordance with the type activity on the single web portal with the option of the first-party audit.

Full textAbstract:
Web pages are typically comprised of different kinds of visual elements such as menus, headers and footers. To improve user experience, eye tracking has been widely used to investigate how users interact with such elements. In particular, eye movement sequences, called scanpaths, have been analysed to understand the path that people follow in terms of these elements. However, individual scanpaths are typically complicated and they are related to specific users, and therefore any processing done with those scanpaths will be specific to individuals and will not be representative of multiple users. Therefore, those scanpaths should be clustered to provide a general direction followed by users. This direction will allow researchers to better understand user interactions with web pages, and then improve the design of the pages accordingly. Existing research tends to provide a very short scanpath which is not representative for understanding user behaviours. This thesis introduces a new algorithm for clustering scanpaths, called Scanpath Trend Analysis (STA). In contrast to existing research, in STA, if a particular element is not shared by all users but it gets at least the same attention as the fully shared elements, it is included in the resulting scanpath. Thus, this algorithm provides a richer understanding of how users interact with web pages. The STA algorithm was evaluated with a series of eye tracking studies where the web pages used were automatically segmented into their visual elements by using different approaches. The results show that the outputs of the STA algorithm are significantly more similar to the inputted scanpaths in comparison with the outputs of other existing work, and this is not limited to a particular segmentation approach. The effects of the number of users were also investigated on the STA algorithm as the number of users required for scanpath analysis has not been studied in depth in the literature. The results show the possibility to reach the same results with a smaller group of users. The research presented in this thesis should be of value to eye tracking researchers, to whom the STA algorithm has been made available to analyse scanpaths, and to behaviour analysis researchers, who can use the algorithm to understand user behaviours on web pages, and then design, develop and present the pages accordingly.

Full textAbstract:
This chapter discusses the relationship between numismatics and archaeology in the later medieval period. It begins by tracing the beginning of the serious study of medieval coins in the eighteenth and nineteenth centuries and discusses the estranged relationship between the disciplines of archaeology and numismatics into the modern period. It demonstrates the vital role that coin hoards have played in the study of the monetary economy of medieval England and Wales and the growth of numismatics as a discipline. However, the emergence of single find evidence (principally metal-detector finds recorded with the Portable Antiquities Scheme) provides us with a new dataset that has the potential to rewrite what we can say about monetization, especially in rural contexts. Imported coins and those used as jewellery or as votive objects are discussed.

The chapter is based on a study of global municipal Web portals conducted through a collaboration between the E-Governance Institute at Rutgers-Newark, USA, and the Global e-Policy e-Government Institute at Sungkyunkwan University in Seoul, South Korea. The joint study ranked municipalities worldwide based on their scores in five e-governance categories of security and privacy, usability, content, services and citizen participation. Crucial trends in the development of the municipal Web portal indicate a growing digital divide between cities belonging to the OECD and non-OECD nations. This chapter attempts to understand the correlates of this divide, by exploring the association of this digital divide to other divides - social, political, economic and literacy divides among nations, particularly those between OECD and non-OECD nations.

Construction: The Construction Transaction Tracking Web Portal is a cutting-edge platform that revolutionizes construction companies' management and monitoring of client transactions. In the fast-paced and dynamic construction world, efficient transaction management is essential for project success, and this web portal aims to streamline the entire process. This software has been designed with the purpose of addressing the challenges associated with the manual maintenance of Construction reports by providing a web-based transaction portal. The system offers comprehensive automation capabilities for converting manual recordings into a web portal interface. The mechanism employed in this context is the utilization of Approvals, which necessitates the approval of both the Super admin and Client in order to validate the transaction. The primary goal is monitoring and overseeing all client construction tasks while ensuring secure management. Having a comprehensive and detailed understanding of the management practices from the previous year can be beneficial. The offered search feature allows users to look for the corresponding client due to the recording of numerous transactions from diverse clients. Moreover, the organization is capable of effectively tackling the issue of manual transactions while also employing cloud technology to ensure the security and integrity of all data. Due to the increased number of transaction records between the Clients and the Super admin in this project, the process of Constructions task tracking transactions has been facilitated.

Full textAbstract:
AbstractThe European Plate Observing System (EPOS) is a large and complex European e-infrastructure that facilitates the integrated use of multi-disciplinary datasets and services for Solid Earth research. EPOS’ GNSS (Global Navigation Satellite Systems) component provides access to GNSS data and products. This paper introduces a new EPOS web portal (https://gnssquality-epos.oma.be) that has been developed with the aim to provide the necessary information to monitor the availability and quality of daily GNSS data that are discoverable through EPOS. Currently, the web portal includes the tracking performances of more than 1600 GNSS stations. Several GNSS data quality indicators (DQIs), such as the number of observed versus expected observations, the number of missing epochs, the number of observed satellites, the maximum number of observations, the number of cycle slips, the Standard Point Positioning results, and the multipath values on code observation are monitored and their plots are available online. These DQIs provide helpful information that can be used to detect a potential degradation of the quality of the GNSS observations. Here, we will present the status of the web portal, the considered data quality indicators, and their benefits for GNSS data users.

Full textAbstract:
Energy Transfer has implemented a new, comprehensive field-inspection system for the pipe inspection lifecycle that encompasses aerial observations, pipe exposures, foreign line crossings, in-line inspections, anomaly remediation, pipe inspection, and integrity sheet generation. In order to ensure the integrity of the pipe inspection program, the field inspection solution required full audit-trail capabilities, front-side data validation, and full integration with the corporate-wide GIS and Engineering Data Management System. Additionally, to ensure the success of the new inspection program, the inspection solution required a highly intuitive and field user-friendly interface, the ability to work equally well in both connected and disconnected environments, interactive mapping functionality, very high reliability, and a process-driven architecture. Energy Transfer owns and operates approximately 43,000 miles of natural gas, natural gas liquids, refined products, and crude oil pipelines. Due to the size and diversity of Energy Transfer’s assets, the corporate GIS system must be distributed across seven independent instances consisting of server pools and large-scale relational database management systems (RDBMS). Although each system must be functionally independent, the field inspection system and the inspection process must interact with each server and RDBMS instance with equal functionality and be able to report on all pipe inspection activities across the enterprise. The inspection system is used by over 1,200 Energy Transfer employees and contractors, and approximately 15,000 inspections are performed annually. The system supports a variety of devices, such as: laptops, tablet computers, iOS devices (i.e., iPads, iPhones), and Android devices. Whether on foot, in vehicles or aircraft, users can enter information from the platform that best meets the needs of their individual environment. Information collected on any device is available for continuance of the pipe inspection lifecycle on any other device and is available in real time at the corporate offices via a Web portal. The Web portal provides visualization tools for both business and engineering analysis such as progress tracking and remediation planning. These functions are supported through the portal’s integrated mapping, dash boarding, and a reporting functionality that includes advanced search capabilities for both comparative and predictive analysis. In addition to utilization for the pipe inspection lifecycle, the inspection system is being used for a variety of other inspection and regulatory compliance-related activities, including: cathodic protection, incident reporting, corrosion assessment, DOT structure location, MAOP-MOP establishment, shallow cover, unmetered gas loss, and many more right-of-way related activities.

Full textAbstract:
Abstract South Oman has several pre-Cambrian reservoirs that are highly pressured (400-1000 bar), deep (3-5 km) and critically sour (H2S up to 10%). The combined STOIIP of these reservoirs makes it one of the largest gas EOR projects in the world. The objective here is to highlight the key performance indicators and digitalization techniques used for continuous and effective well, reservoir and facility management (WRFM) and production optimization, while honoring the facility constraints and gas export requirements. Real time pressure data such as tubing head pressures, injection/production rates along with other data including maps, static pressures and production logs are used to define an appropriate set of performance metric at various levels, e.g. reservoir, sector or well. Digitalization of surveillance data helps in real time production optimization such as offtake management based on creaming curves according to gas sink availability and facility constraints. Key business performance indicators include gas utilization efficiency; MGI performance indicators include incremental oil, throughput, instantaneous and cumulative voidage replacement ratios, gas breakthrough level and time, ratio of reservoir pressure to the target minimum miscibility pressure; and facility constraints are optimized through gas balance, along with tracking field performance against the initial FDP forecasts. Real time performance data is tracked using a commercial Real-Time Data Analysis tool (RTDA) and Database Analytics Visualization Tool (DAVT), with surveillance indicators targeted at well, reservoir and facility level. The above-defined Key Performance Indicators (KPI) are tracked against predictions from the field development plan in web-based portal developed at PDO (Nibras). Digitalization has enabled quick and effective monitoring of these KPI, short-term optimization of injection distribution and offtake rates to maximize oil production and overall value within facilities constraints and varying export gas commitments based on South Oman Gas Line (SOGL) network optimization. Using dimensionless plots and a standardized set of parameters help in developing a common understanding and benchmarking the MGI reservoir response with analogs and amongst different reservoirs. This work presents a set of performance KPIs and short-term optimization methodology using digitalization and LEAN framework that are tracked in a web-based portal, RTDA and DAVT. It provides means to facilitate offtake decisions to meet variable export requirements while honoring facilities constraints, assess reservoir performance, providing valuable insights that helps in speedy reservoir management decisions. This process has been replicated across PDO for all related MGI projects and can benefit other development types, e.g. chemical/steam injection.

Full textAbstract:
Situation-aware software systems open unique perspectives for improved goal achievement characteristics for both users and software suppliers. Such interactive systems give users individualized user experience, provide runtime-adaptive user in-terfaces, allow for situation-dependent task planning capabilities and can trigger ser-vice activations when the situational context changes.Situation-awareness is an evolution of the concept of context-aware computing that was first proposed for distributed mobile computing in [7]. In addition to software responsiveness when dynamically migrating applications to other devices and loca-tions, the notion of context then also included aspects related to the interacting people and the environment.The term situation-awareness was first established in psychology and the cognitive sciences. It was used for describing support systems for human operators in complex situations. By defining situation-dependent requirements correct and smooth interac-tive task accomplishment could be facilitated [3], [4]. For such systems, considering the changes of the interactive context over time plays an important role. The complete cognitive process of perception of the users is dependent on contextual information encountered during the interactive processing of tasks. To capture the individual requirements of a situation, Chang in [1] has suggested that a situation specification must cover the user’s operational environment E, the user’s social behavior B, by interpreting his or her actions, and a hidden context M that includes the user’s mental states and emotions. A situation Sit at a given time t can thus be defined as Sit = <M, B, E>t. A user’s intention for using a specific soft-ware service for reaching a goal can then be formulated as a temporal sequence (Sit1, Sit2, …, Sitn), where Sit1 is the situation that triggers the usage of a service or a task execution and Sitn is the goal-satisfying situation.This model provides a good starting point for the construction of situation-aware applications. However, for recognizing and evaluating situations, the hidden context M, i.e., the user’s emotions, intentions and cognitive load must be made visible and exploitable. Adaptive situation-aware software systems need cognitive and analytic capabilities to interpret the multitude of available emotional and bio-physical signals as well as application and contextual meta-data to being able to infer a goal-reaching set of adaptations.Rather than providing situation-awareness separately for each developed applica-tion, we present an integrated model-based environment for building and running dynamically adaptive situation-aware applications. Therefore, we follow a combined approach by linking the PaMGIS (Pattern-Based Modeling and Generation of Inter-active Systems) MBUID-framework [2] and its domain and user interface models with SitAdapt, a high-resolution observation platform with an integrated user-centric adap-tation component [5]. SitAdapt offers functionality for visual emotion recognition, eye- and gaze-tracking, pulse-rate-tracking, EEG-signal recording, as well as various other bio-physical signal monitoring capabilities. For integrating the necessary rea-soning capabilities, we have introduced situation rules that have access to both, the observed raw-situations, and the modeling resources of the MBUID.We have tested the SitAdapt system with different e-commerce web-applications, e.g., an existing beauty products shopping portal that was enhanced with situation-awareness capabilities and runtime adaptivity [6]. In this environment we also con-ducted two user studies for evaluating the monitoring features and adaptive power of the system with respect to functionality and user experience.In this paper we will discuss the exemplary construction process and runtime-operation of an adaptive situation-aware web-application for travel-booking. We will demonstrate the different steps of the building process that derive application structure and functionality from the task and domain models of the application and apply vari-ous HCI-patterns as well as design and layout models for generating the interactive parts of the source code. We then will describe the observation process that records individual situation profiles during interactive sessions. We will finally discuss the adaptation process that creates a priori adaptations based on the parsing of user and environment models and dynamic runtime-adaptations that are triggered by situation rules fired when a user-specific situation profile encounters conditions that were speci-fied in the situation-rule model of the application. We will conclude the paper with a discussion of ethical and privacy issues arising when confronting users with such powerful monitoring systems. We will also give a short outlook on assessing situation-rule performance and optimizing the rules by implementing a reinforcement learning-component in the future.

Full textAbstract:
In this paper, we argue that setting up a new Digital Public Infrastructure - a National Fraud Portal (NFP) - is the only way to address fraud and consumer scams efficiently. NFPs provide a technological solution as a shared facility for banks, law enforcement, the Financial Intelligence Unit (FIU), the central bank, the conduct supervisor, and other stakeholders. Further down the line, NFPs can connect to one another as cross-border criminal activity increases (a likely consequence of suppressing fraud domestically). The National Fraud Portal (NFP) enables: The real-time tracing and tracking of fund movements across the banking system that allow banks to recover funds for victims quickly The validation and prioritization of cases across the economy using data-driven models The faster identification of new mule accounts at a reduced cost More accurate methods for fraud detection and risk scoring that employ Graph AI deployed on network data. The real-time provision of risk scores and features to banks via APIs, allowing them to improve their fraud models and make faster, more accurate decisions about preventing fraudulent payments before settlement. In this paper, we detail the technological components of the National Fraud Portal. The paper is a result of FNA’s work building technology for National Fraud Portals in Southeast Asia, as well as conversations with over 100 institutions across 20 countries that are actively working on, or have an interest in tackling the problem of fraud and scams.

Tait, Emma, Pia Ruisi-Besares, Matthias Sirch, Alyx Belisle, Jennifer Pontius, and Elissa Schuett. Technical Report: Monitoring and Communicating Changes in Disturbance Regimes (Version 1.0). Forest Ecosystem Monitoring Cooperative, 2021. http://dx.doi.org/10.18125/cc0a0l.
Full textAbstract:
Shifts in disturbance patterns across the Northeast are of increasing concern as the climate continues to change. In particular, changes in patterns of frequency, severity and extent of disturbance event may have detrimental cascading impacts on forest ecosystems and human communities. To explore how changing disturbance regimes might impact future forest health and management it is necessary to understand the historical trends and impacts of disturbance in the region. Although individual types of disturbance have already been analyzed, there is a need for a consolidated overview of the current state of disturbance in northeastern forests. To address this need, the Forest Ecosystem Monitoring Cooperative (FEMC) developed the FEMC: Tracking Shifts in Disturbance Regimes web portal for users to explore changes over time of key disturbance drivers, identify important disturbance responses, and discover where monitoring is happening for both drivers and responses. In collaboration with our advisory committee, we identified key disturbance drivers—flood, high winds, fire, drought, pests—and responses—macroinvertebrates, cold-water fisheries, invasive plants—that are of particular concern in the region. For each of the drivers we identified a suitable regional dataset and analyzed changes over time in frequency, severity, and extent. We also created a structured framework to catalogue programs across the region that are monitoring for these disturbance drivers and responses. Version 1.0 of the FEMC: Tracking Shifts in Disturbance Regimes (https://uvm.edu/femc/disturbance) web portal, first released in October 2021, contains 272 data programs, 11 drivers and three responses. Through the web portal users can browse programs by state, driver type or response type, and explore where monitoring is happening across the region. Driver-specific analyses allow users to quickly see the trends in severity, frequency and extent of selected disturbances and compare the impacts in selected states to regional data. We hope that this collection of programs and the analysis of trends provide researchers and land managers with an easy way to understand the current state of disturbance in northeastern forests that enables them to analyze and plan for future impacts.
