Purpose – This paper aims to understand the interrelationships between the various factors that affect the use of course Web sites by university students in a developing country. The factors considered for the purpose of studying these interrelationships include perceived usefulness, perceived ease of use, perceived Web site credibility and Web site learning acceptance and satisfaction. Furthermore, a comparative study of the potential differences in perceptions between Indian and Omani students with respect to the aforementioned factors is also presented. Design/methodology/approach – A survey instrument was used to collect data from students. Based on an extensive literature review, this paper uses empirical research to analyze student satisfaction in relation to learning through course Websites. Data were analyzed using factor analysis, structural equation modeling and a t-test. Findings – Under the newly proposed construct, Web site credibility was found to be an important predictor of Web site learning acceptance and satisfaction, whereas perceived usefulness and perceived ease of use were mediating variables. In the extended study that compared the relative perceptions of Indian and Omani students, a statistically significant difference in Indian and Omani students was observed for Web site learning acceptance and satisfaction. Practical implications – This study can provide valuable insights for decision-makers that will aid the development of more user-friendly course Web sites for higher education institutions and also promote higher levels of learning, satisfaction and greater course web site usage. Originality/value – This study is probably the first attempt made to observe students’ perceptions of learning via course Web sites in Oman. Furthermore, the use of perceived Web site credibility as a factor in understanding perceptions regarding course Web site learning is a unique feature presented by this paper that is seldom seen in the existing research literature.

Purpose – The purpose of this paper is to improve the general operationalization of an “active patient,” by examining the specific activities and skills expected of active patients. Design/methodology/approach – Expected activities and necessary skills were studied through a qualitative case study into the development and use of an assistive technology (i.e. web site) aimed at stimulating active patient-ship. Interviews, observations and document analysis were used to capture and explore designers’ inscribing practices and their consequences regarding expected competences and activities of patients using the web site. Findings – Designers inscribed two “co-design roles” that active patients were expected to perform on the web site (co-designing their own healthcare and co-designing the healthcare of peers), for which at least eight different competencies were needed. The absence of skills or facilities to apply these skills resulted in incomplete use, a different use than intended by designers and non-use of the web site. Practical implications – Technological choices and inscribing processes determine who is able or facilitated to become active and who is not. Due to inscribed co-design roles, it also influences the extent to which already active peers are able to perform health-related activities. Different users with different conditions should be taken into account in the design as specific group characteristics can influence level of individual activity. Originality/value – This study is, as far as the authors know, the first that examines the “active patient” concept by studying an assistive technology and using scripting literature, resulting in an improved understanding of what it means to become “active” in terms of skills and activities.

The January 6, 2020 insurrection at the United States Capitol Building confirmed and challenged many people’s assumptions about how religion functions in society. As the events of that day continue to be reviewed by government officials, scholars, and public audiences, the Uncivil Religion Project has become an invaluable resource in those endeavors. Spearheaded by Prof. Mike Altman at the University of Alabama and Jerome Copulsky and Peter Manseau from the Smithsonian National Museum of American History, the collaborative web project is both a media-rich digital archive and scholarly anthology on this pivotal historical moment. Altman led a team of graduate students in the University of Alabama’s Religion in Culture MA program in the development of the site. Bulletin editorial assistant Erica Bennet interviewed Ciara Eichorst, Katie Johnson, and Phoebe Duke-Mosier to learn how this project not only took shape, but also impacted their education in the academic study of religion.

Background: Energy Service Companies (ESCOs) for telecommunication sites operate by providing reliable power supply at 100% uptime and billing the mobile operators accommodated on their sites for power usage. To achieve this, there is a need for them to accurately meter the power consumed by connected telecommunication equipment. Method: This work focused on the design and implementation of a remote monitoring agent (RMA) that will pool both power and environmental data from a telecommunication site. The data pool can be presented as real-time data on the RMA’s webpage, it can be downloaded as historical data, and it can be sent to a remote cloud server at regular intervals. The RMA collects both power and environmental data over an RS485 Modbus network and I2C bus respectively. An alternating current (AC) energy meter and a direct current (DC) energy meter were used to harvest the energy data while the environmental data were harvested using a developed Input/Output controller board based on an Atmega328P microcontroller. Raspberry pi was used as the master controller and Node.js was used to build the application running on the master controller. Result: The result showed how both power and environmental data can be harvested from a telecommunication site and locally presented on the web dashboard for real-time monitoring of the site power system. The data could be saved locally on the RMA and downloaded for future use. Conclusion: The implementation of this work provided a prototype of the remote monitoring agent (RMA) that can be deployed by Energy Service Companies (ESCOs) in the telecommunication industry to monitor the usage of the power systems on a cell site.

Abstract. The present article reviews web-based research in psychology. It captures principles, learnings, and trends in several types of web-based research that show similar developments related to web technology and its major shifts (e.g., appearance of search engines, browser wars, deep web, commercialization, web services, HTML5…) as well as distinct challenges. The types of web-based research discussed are web surveys and questionnaire research, web-based tests, web experiments, Mobile Experience Sampling, and non-reactive web research, including big data. A number of web-based methods are presented and discussed that turned out to become important in research methodology. These are one-item-one-screen design, seriousness check, instruction manipulation and other attention checks, multiple site entry technique, subsampling technique, warm-up technique, and web-based measurement. Pitfalls and best practices are described then, especially regarding dropout and other non-response, recruitment of participants, and interaction between technology and psychological factors. The review concludes with a discussion of important concepts that have developed over 25 years and an outlook on future developments in web-based research.

Thesis (MBA)--Stellenbosch University, 2001.ENGLISH ABSTRACT: A multitude of factors affects the experience of the user on a specific site. Slow downloading, navigational difficulties and complex designs all play a role in destroying what could be an enjoyable experience to the user. Usability exists when the design of the system matches what the intended end users need and want. Most Web site designers agree that great design essentially has the user as its priority. Companies tend to forget that the user's hand is on the mouse. The most successful Web sites are those that not only respond to user feedback, but actively seek it out. We have to realise that the cost of flipping to another Web site is so low, it doesn't make any sense for people to go back to a site that failed them the first time. Most Web sites fail miserably at their prime directive: usability. The best way to run a user test is one-on-one, writes Fleming (1998:1). You don't need a large quantity of users for the tests to be effective. The costs in user testing are often exaggerated and there is no excuse for not performing some sort of user test on your Web site. When a page comes up Jakob Nielsen says, people look only one place, in the middle, at the content. (Head, 1999:2) If a page does not appear relevant to the user's current goals, then the user will ruthlessly click the Back button after as little as two to three seconds. Users rarely look at logos, mission statements, slogans, or any other elements they consider fluff. Usability is practically guaranteed if you have a solid information architecture at the outset. Make sure information is not more than two clicks away from the homepage. (Radosevich, 1997:3) According to the GVU7 survey, speed is the number one complaint of Web users (76,5 %). (Hamilton, 1997:1) Since users need web pages to load quickly, you should make your image files small. Try to limit the size of individual images to 5k, and try to limit the total size of all the images on any single page to 20k. Generally, a user with a 28.8 modem should have a sense of the page content or be able to navigate off the page within 10 seconds of download. The rest of the page should load within the next 30 seconds. Any site needs a good search feature since even the best navigation support will never be enough. (Nielsen, 1996a: 1) A search function should be provided if the site has more than 100 pages. Even if you haven't created perfect navigation, at least be consistent. (Berst, 1998: 1) The Back button is the lifeline of the Web user and the second-most used navigation feature (after following hypertext links). People rarely read web pages word by word - they scan pages to find the information they want. Make the text scannable with bulleted lists, highlighted keywords, meaningful headings, and short sections of text. The essential purpose of graphics, especially animated graphics, is to set the tone and communicate the company's personality in a unique and fun way. (Heath, 1997:1)
AFRIKAANSE OPSOMMING: 'n Menigte faktore beïnvloed die gebruiker se ondervinding van 'n spesifieke Webblad. Aflaai spoed, navigasie en komplekse bladontwerp kan almal 'n gebruiker se belewenis van 'n Webblad verongeluk. Bruikbaarheid (Usability) bestaan wanneer die ontwerp van die sisteem voldoen aan die behoeftes van die eindgebruiker. Web ontwerpers het dit eens dat goeie ontwerp die gebruiker se behoeftes as prioriteit sien. Maatskappye vergeet dikwels dat die gebruiker se hand die muis beheer. Die mees suksesvolle Webblaaie is nie net die wat reageer op verbruiker terugvoer nie maar dit selfs aanmoedig. Ons moet verstaan dat dit so maklik is om na 'n volgende Webblad te spring dat dit nie sin maak om terug te keer na 'n Webblad wat jou eenkeer in die steek gelaat het nie. Die meeste Webblaaie misluk tragies in hul poging tot bruikbaarheid. Die beste gebruikerstoets metode is een-tot-een, skryf Heming (1998: 1) Die toets lewer betekenisvolle resultate selfs met enkele gebruikers. Nielsen sê gebruikers stel deesdae net in inligting belang. Indien inligting irrelevant voorkom sal die gebruiker nie skroom om die "Back" sleutel te gebruik nie. Gebruikers kyk selde na logos, missie stellings en slagspreuke en beskou dit as onbenullighede. Maak seker dat inligting nie meer as twee klikke vanaf die tuisblad is me. (Radosevich, 1997:3) Die GVU7 studie het bevestig dat aflaaispoed die gebruikers se grootste beswaar is.(Hamilton, 1997: 1) Enige Webblad benodig 'n goeie soek ("search") funksie veral as die Webwerf meer as 100 bladsye het. Die "back" sleutel is die reddingslyn van die gebruiker en die tweede mees gebruikte sleutel op navigasiestelsel. Gebruikers lees selde woord vir woord wat voor hulle staan, maar skandeer eerder 'n blad. Hou dus teks kort, met kort sinsnedes en kort kragtige begrippe. Grafieke se hoofdoel is om Webblad atmosfeer op unieke wyse te skep.(Heath,1997:1)

ZusammenfassungDer Ausbau der Windenergie findet zunehmend im Wald statt, da hier häufig windhöffige und damit ökonomisch attraktive Standorte zu finden sind. Allerdings ist hier der Konflikt mit dem Artenschutz im Allgemeinen und dem Fledermausschutz im Speziellen besonders hoch. In diesem Beitrag beleuchten wir vor dem Hintergrund des gesetzlich vorgegebenen normativen Rahmens den artenschutzrechtlichen Teil der Windkraftplanung im Wald mit Bezug auf Fledermäuse – von der Untersuchungsplanung über die eingesetzten Methoden bis zur Bewertung. Bezogen auf Fledermäuse stehen hier insbesondere die Vermeidung der direkten Tötung sowie die Verminderung der Beeinträchtigung ihres Lebensraums im Fokus der Betrachtung. Bundesland-spezifische Arbeitshilfen stecken den Untersuchungsumfang, die einzusetzenden Erfassungsmethoden und den räumlichen und zeitlichen Untersuchungsrahmen ab. Sie empfehlen zudem Maßnahmen zur Kompensation potenziell negativer Auswirkungen eines Eingriffs. Ihr Effekt auf die methodische Qualität der Fachbeiträge zu Fledermäusen ist jedoch gering. Meist kommen im Rahmen der speziellen artenschutzrechtlichen Prüfung zu Fledermäusen die Quartierbaumsuche, Netzfang, unterschiedliche Varianten des akustischen Monitorings (aktiv und passiv) sowie die Radiotelemetrie zum Einsatz. Insbesondere bei der bevorzugt empfohlenen akustischen Erfassung mindern zahlreiche methodische Probleme auf der technischen und der analytischen Ebene die Aussagekraft. Auch der Erfolg des Fangs von Fledermäusen mit Netzen hängt von zahlreichen Parametern ab. Die Quartierbaumerfassung lässt sich in ihrem Erfolg deutlich durch die Radiotelemetrie verbessern. Zur sinnvollen Quantifizierung des Lebensraumanspruchs einer Fledermauspopulation jedoch werden mittels Radiotelemetrie in der Regel zu wenige Tiere zu kurz untersucht. Die Bewertung der erhobenen Daten, hier gezeigt anhand akustisch ermittelter Aktivitätsdichten, erfolgt subjektiv, da Bewertungskriterien fehlen. Die am häufigsten empfohlenen und somit umgesetzten Methoden der Konfliktvermeidung und -minimierung sind CEF- (= Continued Ecological Function) und FCS-Maßnahmen (= Favourable Conservation Status) sowie das Gondelmonitoring und die selektive Abschaltung der WEA. Auch diese Maßnahmen entfalten z. T. Schwächen; die Bewahrung und Entwicklung von Waldstandorten als/zu ökologisch wertvollen Lebensräumen sowie die Verminderung der Schlagopferzahl durch spezielle Algorithmen (ProBat-Tool) sehen wir jedoch als sinnvoll an. Abschließend formulieren wir Anregungen zur Verbesserung und Objektivierung der Eingriffsplanung von WEA im Wald.SummaryThe development of wind energy is concentrating in forests, as windy and thus economically favourable sites can often be found here. However, the conflict with species conservation in general and bat conservation in particular is especially high in forests. We here examine the impact assessment on bats in the context of the legally prescribed normative framework in wind farm planning in the forest – from the study design to the methods used and the assessment itself. With regard to bats, the focus here is on avoiding direct killing and reducing the impairment of their habitat. Guidance documents for the German federal states define the extent of the surveys, the survey methods, and the spatial and temporal scope of a survey. They also recommend measures to compensate for potential negative impacts of wind energy plants (WEP). However, their effect on the quality of the expert reports on bats is low. In most cases, the search for roost trees, mist netting, different types of acoustic monitoring (active and passive) and radio tracking are used. In particular, numerous methodological problems at the technical and analytical levels reduce the validity of acoustic surveys. The success of mist netting bats also depends on numerous parameters. The success of roost tree surveys can be significantly improved by radio tracking. However, for a meaningful quantification of the habitat requirements of a bat population, radio tracking is usually used on too few animals for too short a time. The evaluation of the collected data, shown here on the basis of acoustically determined activity densities, is subjective because evaluation criteria are lacking. The most frequently recommended and thus implemented methods of conflict mitigation are CEF (= Continued Ecological Function and FCS (= Favourable Conservation Status) measures as well as nacelle monitoring and selective shut-down of wind turbines. These measures also show some weaknesses, but we consider the maintenance and development of forest sites as or into ecologically valuable habitats, as well as the reduction of the number of bat fatalities by means of specific algorithms (ProBat tool), to be sensible. Finally, we make suggestions for improving and objectifying the impact assessment of wind-energy facilities in forests.

Many recent developments in mixed reality applications are exploited for research on improving training in the construction industry. While immersive technologies offer indisputable advantages over classic paper- or multi-media-based training material, access to this kind of technology is still very limited in the academic world and even less widespread in industry. In this paper, the authors follow the current trend of creating low-threshold micro-learning nuggets, which are easily consumable on mobile devices but can be accessed in every web browser. This is essential to reach the construction trade workforces, which for the most part will own a smart or mobile device, but neither specialized equipment, nor will there be time or patience for a lengthy setup phase before learning content consumption. The learning content aims to give construction workers a clear vision of what some of the fundamental components of a sustainable construction site should look like and what role they play in achieving the said vision. The learning content revolves around the initial idea of DGNB certification (German: German Sustainable Building Council), waste management, certification of construction wood, handling of harmful substances and chemicals and some general health and safety regulations that impact the emission of dust, noise and vibration. The paper describes the general approach of the planning, orchestration of learning material, development of the learning nugget, and deployment, as well as a study for acceptance and user experience

Many recent developments in mixed reality applications are exploited for research on improving training in the construction industry. While immersive technologies offer indisputable advantages over classic paper- or multi-media-based training material, access to this kind of technology is still very limited in the academic world and even less widespread in industry. In this paper, the authors follow the current trend of creating low-threshold micro-learning nuggets, which are easily consumable on mobile devices but can be accessed in every web browser. This is essential to reach the construction trade workforces, which for the most part will own a smart or mobile device, but neither specialized equipment, nor will there be time or patience for a lengthy setup phase before learning content consumption. The learning content aims to give construction workers a clear vision of what some of the fundamental components of a sustainable construction site should look like and what role they play in achieving the said vision. The learning content revolves around the initial idea of DGNB certification (German: German Sustainable Building Council), waste management, certification of construction wood, handling of harmful substances and chemicals and some general health and safety regulations that impact the emission of dust, noise and vibration. The paper describes the general approach of the planning, orchestration of learning material, development of the learning nugget, and deployment, as well as a study for acceptance and user experience

Poor construction quality is one of the most significant challenges for the construction industry. However, failures can be avoided or minimized by inspections based on detailed quality inspection plans as a part of quality assurance. Therefore, structured and project-specific planning of inspection plans is required to provide inspectors with the right information. Nevertheless, inspection planning is mainly manual, dependent on the individual’s experience and high level of effort. As a result, inspection planning is often neglected and limited to providing general checklists that often lack semantically rich descriptions and are unspecific concerning individual project requirements. Furthermore, proper planning of inspections requires multiple information sources, such as building design, schedules, contractual and supplier guidelines, and standards, all of which must be provided or linked via an information model. Current research lacks an adequate formalized knowledge model to provide the knowledge-driven inspection planning process with the necessary domain knowledge to support inspection planning with heterogeneous information defined in isolated systems. Therefore, this paper extends the Ontology for Construction Quality Assurance (OCQA) with the OCQA-Thermal Insulation (OCQA-TI) to formalize thermal insulation inspection planning knowledge. The OCQA offers a new linked data model that provides explicit knowledge of quality inspection planning. The development of the OCQA-TI follows the Linked Open Terms (LOT) methodology and is implemented using the Web Ontology Language (OWL). The proposed ontology is evaluated using various approaches, including automatic consistency checking, answering competency questions, and criteria-based evaluation. The results indicate that the OCQA-TI can provide inspectors with relevant inspection planning knowledge and integrate various related information streams, thus providing a more comprehensive and efficient approach to insulation inspection planning. The functionality of OCQA-TI enables the fulfillment of increased sustainability and energy efficiency requirements by providing insulation inspection knowledge

AbstractAs it is known, the global phenomenon of rising temperatures causes uncomfortable and often harmful conditions for human beings living in moderate-climate zones, such as the Mediterranean area, especially in the hottest periods. Examinations of metropolitan cities can witness that high temperatures generate Urban Heat Island (UHI), due to population, buildings, vehicles and human activities in general. With the increase of rising temperatures in the latest decades, people living in big cities have gotten used to tackling heat discomfort with electricity charged cooling systems. As a result, the energy consumption for air-conditioning causes UHIs’ effects to further grow. It is scientifically confirmed that the behavioral habit of relying on artificially generated cold whenever temperatures rise will eventually make the climate crisis more problematic in the near future. Energy communities are used to producing, storing and consuming energy on site; therefore, power sources must be in close proximity to users. Albeit neglected in the Modern Era, the most proximate and sustainable energy supply is directly available to us: sunlight. The origin of hot temperatures, discomfort and energy waste is, indeed, the most exploitable power generator men can access to. In Southern Europe or Middle East cities, the use of veils as urban-scale shading devices is part of the consolidated tradition; a well-known example can be found in the Spanish city of Sevilla, where textile curtains named “Sevillans” are stretched between buildings. At the present time, we’re witnessing that the climate mitigation action of shading systems can be pursued in combination with energy production, with the development of membrane integrated flexible photovoltaic cells (PV). Masdar City in the United Arab Emirates, designed by the Foster Studio, or the Solar trees of the German pavilion at EXPO 2015 in Milan and the Promenade of the EXPO 2021 in Dubai are some innovative yet relevant cases. The use of PV cells for sun-shielding purposes is optimal to respond to a double-sided problem with a single object. Manufacturing an adaptive velario using composite fibers (i-Mesh), could both allow us to design the shape and modulate the density of integrated PV cells as needed. Method: To identify the best position for the adaptive tensile canopies, it is necessary to superimpose different site-specific data: temperatures in the urban area, in particular close to buildings; surfaces that receive most of the daytime radiation; sunlight and ventilation. To develop the most suitable solutions to many environmental scenarios, three-dimensional simulations performed with virtual models must be used both at urban (Envimet) and at building scale (in-Sight). Expected results: An algorithm capable of determining the “Velari” best position and the proper shading/density factor. A model, applied to a case study in Rome, to serve an evaluation of the benefits of this technology in terms of decreasing surface temperatures of external horizontal and vertical surfaces of buildings and streets.

Web site usability is concerned with how easy and intuitive it is for individuals to learn to use and interact with a Web site. It is a measure of the quality of a Web site’s presence, as perceived by users. The usability of Web sites is important, because high usability is associated with a positive attitude toward the Web site and results in higher online transactions. Poorly designed Web sites with low usability, on the other hand, lead to negative financial impacts. Existing approaches to Web site usability include measurement and tracking of parameters, such as response time and task completion time, and software engineering approaches that specify general usability guidelines and common practices during software development. This paper analyzes usability from the point of view of Web site design parameters. An analysis of usability and other design characteristics of 200 Web sites of different kinds revealed that design aspects, such as information content, ease of navigation, download delay, and Web site availability positively influence usability. Web site security and customization were not found to influence usability. The paper explains these results and suggests design strategies for increasing Web site usability.

Feral systems have largely been regarded as the users' response to discrepancies between official IT software systems and actual business processes. Inadequacies, discrepancies, and absence of systems support to work processes might lead to users initiating systems development themselves: systems involving any combination of software and manual processes. Feral systems are unofficial and exhibit a conflict between formal and actual operational implementation. In this chapter, the use and implementation of feral systems in Denmark are analysed and discussed. It is found interesting to aim for an understanding of feral systems in a small, relatively agile economy with traditionally positive to rapid adoption of information technology in enterprises. The method being used is qualitative case studies in selected companies representing various complexities of their respective business models and industries. The case studies address both issues of organisational and technological nature of the feral systems typically with an offset in the companies' overall information systems architecture. Among findings are (1) feral systems as a known choice when reflecting business processes with open and non-routinised character, (2) a general acceptance not related to the size or industry, (3) feral systems have received attention as implementations of innovation, (4) feral systems start as opposed to formal and official systems, but during their lifetime they can drift towards a more official status, and (5) feral systems are accepted as low-cost solutions to fill gaps in business process support where ERP systems come short.

Abstract There have been widespread interests in the development and application of World Wide Web (WWW) to support decision-making activities in product design and manufacture. An increasing number of web applications are emerging and a large number of practitioners are keen on trying these web-based decision support systems. In the meanwhile, it becomes increasingly difficult to surf for appropriate web applications on the Internet with general-purpose search engines. This paper describes a web site, WAPIP, that has been developed specifically to support new product introduction activities. It provides databases for software vendors and researchers to register their web applications with the “wapip” search engine. It also provides facilities to support practitioners in product design and manufacture to search rapidly for the right web applications suitable for solving their problems. This paper discusses the various issues regarding the design, development and operation of this “wapip” search engine.

Abstract Various approaches to capturing and retrieving engineering design information and intent are currently used in industry and play an important role in engineering design collaboration and concurrent engineering. At one end of the spectrum there are expert systems that perform complex analyses of designs based on information that is very specific and specialized for a particular product. At the other end are less automated and less complex non-expert systems. These systems provide the means to organize, collect, and reuse general collections of design intent and rationale in terms of notes, solutions to problems previously encountered, and best practices organized into a database or posted on an internal web site. By surveying the current state of engineering design knowledge management (KM) tools and implementation, conclusions can be drawn regarding the basic elements of successful knowledge management and the opportunities that exist to expand the capabilities and use of such systems in the product development environment. This is of particular relevance to current design practices that are becoming increasingly automated, decentralized, and global. Knowledge management on a large scale will require strategic planning and a deeper understanding to provide the standards for interoperability and exchange that will be needed. This paper provides an overview of approaches to knowledge management in the product development environment.

The Internet presents an opportunity to facilitate the design of pressure equipment in a new and different way. Current industrial design practice employs computer programmes that perform design-by-formula (DBF) calculations in accordance with ASME VIII Division 1 or other international codes and standards. Design-by-analysis (DBA), however is only undertaken by experienced vessel engineers or general finite element analysis (FEA) consultancy specialists. The present work has established an interface between the Internet and a commercial FEA program for use by designers in the pressure vessel industry. The interface allows users to input variables for a pre-delivered model, obtained from a library of verified models, which may be analysed automatically and the results returned for review. The outcome of the work has been that an interface has been fully established in the form of an interactive dynamically operating web site. It has extensive error checking facilities for user input variables, and is fully operational for the available models, which, for example, includes a reinforced nozzle located in an elliptical end with multiple loadings. The system has been tested by industry and new opportunities have resulted for the training of engineers by allowing access to complex models only after suitable training has been undertaken and levels of competence have been achieved.

Abstract The Anchor semi-submersible floating production unit (FPU) is a Chevron operated Gulf of Mexico (GOM) deepwater facility with a nameplate capacity of 75,000 bopd and 28 mmscfd and future expansion capability. This paper provides an overview of the FPU from detailed design through fabrication including design philosophy, equipment selection, pre-investment, and construction methodology as well as insights into Anchor’s contracting and execution strategy. Principles such as minimum functional objective (MFO), conditions precedent (CP), and on-ground max are discussed, as are some of the key decisions that enabled successful delivery of the Anchor FPU such as early contractor engagement and implementation of a rigorous weight management program. Final investment decision (FID) for the Anchor project was reached in 4Q2019 and soon after in early 2020, the world began to experience impacts from the COVID-19 global pandemic. Actions taken by the Anchor project team to address the many challenges of executing a major capital project (MCP) during a global pandemic and market downturn will also be shared. Anchor followed a general contracting strategy similar to past projects executed by Chevron in the GOM. While this approach requires a larger Owner’s team to manage multiple contracts and interfaces, it also provides greater visibility and earlier recognition of potential execution challenges thereby enabling the project team to react faster with direct input to mitigate or address issues as soon as they are identified. A large number of contracts were executed to deliver the FPU including separate topsides engineering, hull engineering, topsides fabrication and integration, hull fabrication, and systems completion contracts. The Anchor hull was fabricated in South Korea and transported via a heavy transport vessel to the Anchor topsides fabrication site in the US Gulf Coast where the topsides was integrated to the hull. Construction was completed in May 2023 and the Anchor FPU was wet towed from the fabrication yard to its final location in the GOM for installation and execution of the offshore hookup & commissioning (HUC) campaign. For clarity, the following terms are used throughout this paper. High Pressure High Temperature (HPHT) refers to equipment rated to pressures greater than 15,000 psi and/or temperatures equal to or greater than 350°F. Anchor is a high pressure project under the HPHT category. 20K refers to the Anchor project’s technology development and qualification program.

With the rapid advancement of computing technology, the paradigm of learning has been changed from the classroom environment to the web environment. The support software for e-learning is key to implementing such a web-based learning paradigm. In this paper, a general approach to construct an elearning software system is proposed and described. The approach is based on an analogy between e-learning and mass customization product design. In the case of mass customization product design, customers can participate in a product design and realization process regardless of temporal and spatial restrictions. In the case of e-learning, learners can access a virtual teaching center at any time and at any place. This analogy has further led us to exploit fruitful developments in computer software for mass customization, in particular, a so called web-based configuration design system through the constraint satisfaction problem (CSP) approach. This paper discusses both conceptual development and implementation. An illustration is given for implementation.

In general, the design process involves envisioning and developing concepts for a component or system, combining these fractions into an integrated whole and evaluating the final design against functional requirements. A major challenge is developing components or systems to a level of maturity that permits feasibility evaluation of the integrated whole while optimizing opposing performance functions (e.g., thick for strength, but thin for heat transfer). Economic pressure often drives design concepts to conservative bases early in the process. The approach presented in this paper is a highly cost-effective means of developing alternative design solutions for given set of design requirements — in this case a radioactive materials transportation package. In response to planned phase-out of the Department of Transportation 6M specification package, an internal competition was held at the Savannah River Site to develop design proposals for the 6M replacement. Two teams were provided with design requirements, design evaluation criteria, a limited budget and short time frame to develop proposals for a General Purpose Fissile Package (GPFP). Resulting GPFP designs, while quite different, met the performance requirements, were economical, operator friendly, light weight, certifiable, and able to accommodate a wide range of radioactive materials. The methodology of an in-house design competition proved to be a very cost effective way of advancing design alternatives from design requirements to practical design proposals. Estimated fabrication costs for each of the designs are significantly less than other packages currently available for the proposed service.

In this paper, concept of developing a haptic tele-robotic master-slave manipulators for ultrasound imaging examination, and some preliminary results will be presented. In a tele-ultrasound system the motion of a master manipulator (such as a haptic wand or a simple joystick) which carries a virtual probe is controlled by a medical expert and remotely reproduced at the patient site by a slave robot, carrying the ultrasound probe. In general a remote diagnostic system contains three divisions: expert station (or expert site), patient station (or patient site), and a communication network such as servers Wi-Fi or satellite network. The experiments demonstrate that the slave manipulator is capable of successfully following the motion of a master manipulator in a path following as well as for point-to-point motions.

The Smart Energy Design Assistance Center assessed the administrative, technical, and economic aspects of feasibility related to the procurement and installation of photovoltaic solar systems on IDOT-owned buildings and lands. To address administrative feasibility, we explored three main ways in which IDOT could procure solar projects: power purchase agreement (PPA), direct purchase, and land lease development. Of the three methods, PPA and direct purchase are most applicable for IDOT. While solar development is not free of obstacles for IDOT, it is administratively feasible, and regulatory hurdles can be adequately met given suitable planning and implementation. To evaluate IDOT assets for solar feasibility, more than 1,000 IDOT sites were screened and narrowed using spatial analytic tools. A stakeholder feedback process was used to select five case study sites that allowed for a range of solar development types, from large utility-scale projects to small rooftop systems. To evaluate financial feasibility, discussions with developers and datapoints from the literature were used to create financial models. A large solar project request by IDOT can be expected to generate considerable attention from developers and potentially attractive PPA pricing that would generate immediate cash flow savings for IDOT. Procurement partnerships with other state agencies will create opportunities for even larger projects with better pricing. However, in the near term, it may be difficult for IDOT to identify small rooftop or other small on-site solar projects that are financially feasible. This project identified two especially promising solar sites so that IDOT can evaluate other solar site development opportunities in the future. This project also developed a web-based decision-support tool so IDOT can identify potential sites and develop preliminary indications of feasibility. We recommend that IDOT begin the process of developing at least one of their large sites to support solar electric power generation.

The existing foundations of a bridge can sometimes be reused. This may occur when a completely new bridge is built but also in bridge or superstructure widening projects. Reuse of existing foundations not only eliminates the costs associated with demolishing and disposing of old foundations, but also reduces the costs of the design and construction of new foundation elements. However, several challenges exist, including assessing the structural integrity, estimating the current capacity, estimating the remaining service life, and considering current design codes and specifications of the existing foundations, and clear guidelines for foundation reuse. The absence of foundation reuse guidelines by INDOT hinders the reuse of bridge foundations and prevents design consultants from designing new structures using existing foundations. In this project, comprehensive foundation reuse guidelines were developed in the form of flow charts based on a literature review on bridge foundation reuse design—including technical publications and existing standards and codes—and a set of analyses. The proposed guidelines include detailed guidance on inspection of the structural integrity of existing foundations, determination of as-built geometry of existing foundations, capacity estimation of existing foundations, minimum requirements for foundation reuse, and selection of foundation reuse solutions. The proposed guidelines for foundation reuse design were tested in an ongoing INDOT project. From the implementation project, we found that a complete site investigation that produces reliable estimation of soil profile and properties, is essential to determine whether there is reserve capacity in existing foundations. Additional site investigation is generally worth doing, not only to account for any strengthening of the soil that may have occurred over time, but also because of the greater accuracy in interpretation and analysis that results. We also found that use of the most current, cutting-edge methods can be useful in estimating the reserve capacity of existing foundations, and that design checks using different design codes can produce contrasting results.

Odonates are significant components of most wetland habitats and important indicators of their health. At Cape Cod National Seashore (CACO), we compiled odonate records dating back to the 1980s and, based partly on that data, identified 41 wetland sites for sampling, representing six freshwater habitats (kettle pond, inter-dune pond, dune slack, riparian marsh, vernal pool, and bog). We surveyed these sites for adult odonates during the 2016?2018 field seasons. Ten sites were surveyed all three years (total 19-20 surveys/site); all ten had at least some historical data. The remaining 31 sites were surveyed for one field season, a total of 6-8 times each. We conducted 391 surveys, recording 53,435 individuals and 74 species (45 dragonflies and 29 damselflies); not all individuals were identified to species. Abundance and species richness varied significantly between habitats. For all individuals recorded, abundance was greatest at vernal pools and kettle ponds. Riparian sites had the lowest abundance. Species richness was highest at kettle ponds, including several species of conservation concern, two listed as Threatened by the state of Massachusetts. Riparian marshes and dune slacks had relatively low richness. Among the 10 sites surveyed three years, we found significant annual variation in abundance and species richness. There was significant and generally greater between-site variation in abundance within a year than between years at sites. Community analysis found pond depth, habitat type, and presence of predaceous fish were significant factors explaining between-site variation in community composition. Habitats also differed significantly in community composition. Multidimensional scaling showed sites tend to cluster together by habitat type. Vernal ponds have the highest average community similarity to all other habitats (53.5%), with dune slack (52.9%), bog (52.0%) and inter-dune (51.5%) close behind. In contrast, riparian sites (46.3%) and kettle ponds (39.5%) are least similar to other habitats. Overall, 86 species of odonates have been recorded at CACO, a rich and diverse assemblage reflecting the variety and quality of freshwater habitats present. Although these habitats are relatively well-protected, stressors include climate change, nutrient inflow from adjacent development, road runoff, and trampling of emergent vegetation. A plan for monitoring is beyond the scope of this project. Ideally, it would be best to use the insight into odonate variation obtained from these surveys to develop a monitoring program designed to meet standards of statistical confidence and power currently employed in NPS monitoring programs.

Our original objectives were to assess the unexplored dimension of alternative splicing as a source of genetic variation. In particular, we sought to initially establish an alternative splicing database for Arabidopsis, the only plant for which a near-complete genome has been assembled. Our goal was to then use the database, in part, to advance plant gene prediction programs that are currently a limiting factor in annotating genomic sequence data and thus will facilitate the exploitation of the ever increasing quantity of raw genomic data accumulating for plants. Additionally, the database was to be used to generate probes for establishing high-throughput alternative transcriptome analysis in the form of a splicing-specific oligonucleotide microarray. We achieved the first goal and established a database and web site termed Alternative Splicing In Plants (ASIP, http://www.plantgdb.org/ASIP/). We also thoroughly reviewed the extent of alternative splicing in plants (Arabidopsis and rice) and proposed mechanisms for transcript processing. We noted that the repertoire of plant alternative splicing differs from that encountered in animals. For example, intron retention turned out to be the major type. This surprising development was proven by direct RNA isolation techniques. We further analyzed EST databases available from many plants and developed a process to assess their alternative splicing rate. Our results show that the lager genome-sized plant species have enhanced rates of alternative splicing. We did advance gene prediction accuracy in plants by incorporating scoring for non-canonical introns. Our data and programs are now being used in the continuing annotation of plant genomes of agronomic importance, including corn, soybean, and tomato. Based on the gene annotation data developed in the early part of the project, it turned out that specific probes for different exons could not be scaled up to a large array because no uniform hybridization conditions could be found. Therefore, we modified our original objective to design and produce an oligonucleotide microarray for probing alternative splicing and realized that it may be reasonable to investigate the extent of alternative splicing using novel commercial whole genome arrays. This possibility was directly examined by establishing algorithms for the analysis of such arrays. The predictive value of the algorithms was then shown by isolation and verification of alternative splicing predictions from the published whole genome array databases. The BARD-funded work provides a significant advance in understanding the extent and possible roles of alternative splicing in plants as well as a foundation for advances in computational gene prediction.

This document analyzes the results of a Web-based survey conducted by the Research Department to assess how the IDB is viewed by political and corporate leaders in the region. The questionnaire included 31 questions that compared the IDB to the IMF, World Bank, CAF, BCIE and CDB. The sample includes the responses of 336 representatives from the 26 Latin American and Caribbean IDB member countries. In general, the IDB has a better image than the other multilateral organizations in understanding development problems and contributing to their solutions. Its main comparative advantage is in the design of social service projects (education, health and social security). The IDB also is clearly perceived to outperform its peers in public sector modernization and infrastructure projects. The IDBs weakest areas are related to its efficiency (lengthy loan approvals) and efforts to help discipline macroeconomic and other policies. Respondents believe that all international organizations should expand their technical assistance and knowledge activities not tied to projects or loans. For the IDB, the survey results also assign a high priority to increasing projects in social areas.

Background: In an era of explosive growth in biomedical evidence, improving systematic review (SR) search processes is increasingly critical. Text-mining tools (TMTs) are a potentially powerful resource to improve and streamline search strategy development. Two types of TMTs are especially of interest to searchers: word frequency (useful for identifying most used keyword terms, e.g., PubReminer) and clustering (visualizing common themes, e.g., Carrot2). Objectives: The objectives of this study were to compare the benefits and trade-offs of searches with and without the use of TMTs for evidence synthesis products in real world settings. Specific questions included: (1) Do TMTs decrease the time spent developing search strategies? (2) How do TMTs affect the sensitivity and yield of searches? (3) Do TMTs identify groups of records that can be safely excluded in the search evaluation step? (4) Does the complexity of a systematic review topic affect TMT performance? In addition to quantitative data, we collected librarians' comments on their experiences using TMTs to explore when and how these new tools may be useful in systematic review search¬¬ creation. Methods: In this prospective comparative study, we included seven SR projects, and classified them into simple or complex topics. The project librarian used conventional “usual practice” (UP) methods to create the MEDLINE search strategy, while a paired TMT librarian simultaneously and independently created a search strategy using a variety of TMTs. TMT librarians could choose one or more freely available TMTs per category from a pre-selected list in each of three categories: (1) keyword/phrase tools: AntConc, PubReMiner; (2) subject term tools: MeSH on Demand, PubReMiner, Yale MeSH Analyzer; and (3) strategy evaluation tools: Carrot2, VOSviewer. We collected results from both MEDLINE searches (with and without TMTs), coded every citation’s origin (UP or TMT respectively), deduplicated them, and then sent the citation library to the review team for screening. When the draft report was submitted, we used the final list of included citations to calculate the sensitivity, precision, and number-needed-to-read for each search (with and without TMTs). Separately, we tracked the time spent on various aspects of search creation by each librarian. Simple and complex topics were analyzed separately to provide insight into whether TMTs could be more useful for one type of topic or another. Results: Across all reviews, UP searches seemed to perform better than TMT, but because of the small sample size, none of these differences was statistically significant. UP searches were slightly more sensitive (92% [95% confidence intervals (CI) 85–99%]) than TMT searches (84.9% [95% CI 74.4–95.4%]). The mean number-needed-to-read was 83 (SD 34) for UP and 90 (SD 68) for TMT. Keyword and subject term development using TMTs generally took less time than those developed using UP alone. The average total time was 12 hours (SD 8) to create a complete search strategy by UP librarians, and 5 hours (SD 2) for the TMT librarians. TMTs neither affected search evaluation time nor improved identification of exclusion concepts (irrelevant records) that can be safely removed from the search set. Conclusion: Across all reviews but one, TMT searches were less sensitive than UP searches. For simple SR topics (i.e., single indication–single drug), TMT searches were slightly less sensitive, but reduced time spent in search design. For complex SR topics (e.g., multicomponent interventions), TMT searches were less sensitive than UP searches; nevertheless, in complex reviews, they identified unique eligible citations not found by the UP searches. TMT searches also reduced time spent in search strategy development. For all evidence synthesis types, TMT searches may be more efficient in reviews where comprehensiveness is not paramount, or as an adjunct to UP for evidence syntheses, because they can identify unique includable citations. If TMTs were easier to learn and use, their utility would be increased.

Multi-Dimensional Infiltration and Distribution of Water of Different Qualities and Solutes Related Through Artificial Neural Networks.

The project exploits the use of Artificial Neural Networks (ANN) to describe infiltration, water, and solute distribution in the soil during irrigation. It provides a method of simulating water and solute movement in the subsurface which, in principle, is different and has some advantages over the more common approach of numerical modeling of flow and transport equations. The five objectives were (i) Numerically develop a database for the prediction of water and solute distribution for irrigation; (ii) Develop predictive models using ANN; (iii) Develop an experimental (laboratory) database of water distribution with time; within a transparent flow cell by high resolution CCD video camera; (iv) Conduct field studies to provide basic data for developing and testing the ANN; and (v) Investigate the inclusion of water quality [salinity and organic matter (OM)] in an ANN model used for predicting infiltration and subsurface water distribution. A major accomplishment was the successful use of Moment Analysis (MA) to characterize “plumes of water” applied by various types of irrigation (including drip and gravity sources). The general idea is to describe the subsurface water patterns statistically in terms of only a few (often 3) parameters which can then be predicted by the ANN. It was shown that ellipses (in two dimensions) or ellipsoids (in three dimensions) can be depicted about the center of the plume. Any fraction of water added can be related to a ‘‘probability’’ curve relating the size of the ellipse (or ellipsoid) that contains that amount of water. The initial test of an ANN to predict the moments (and hence the water plume) was with numerically generated data for infiltration from surface and subsurface drip line and point sources in three contrasting soils. The underlying dataset consisted of 1,684,500 vectors (5 soils×5 discharge rates×3 initial conditions×1,123 nodes×20 print times) where each vector had eleven elements consisting of initial water content, hydraulic properties of the soil, flow rate, time and space coordinates. The output is an estimate of subsurface water distribution for essentially any soil property, initial condition or flow rate from a drip source. Following the formal development of the ANN, we have prepared a “user-friendly” version in a spreadsheet environment (in “Excel”). The input data are selected from appropriate values and the output is instantaneous resulting in a picture of the resulting water plume. The MA has also proven valuable, on its own merit, in the description of the flow in soil under laboratory conditions for both wettable and repellant soils. This includes non-Darcian flow examples and redistribution and well as infiltration. Field experiments were conducted in different agricultural fields and various water qualities in Israel. The obtained results will be the basis for the further ANN models development. Regions of high repellence were identified primarily under the canopy of various orchard crops, including citrus and persimmons. Also, increasing OM in the applied water lead to greater repellency. Major scientific implications are that the ANN offers an alternative to conventional flow and transport modeling and that MA is a powerful technique for describing the subsurface water distributions for normal (wettable) and repellant soil. Implications of the field measurements point to the special role of OM in affecting wettability, both from the irrigation water and from soil accumulation below canopies. Implications for agriculture are that a modified approach for drip system design should be adopted for open area crops and orchards, and taking into account the OM components both in the soil and in the applied waters.

Our project focuses on gene expression and proteomics of the whitefly Bemisia tabaci (Gennadius) species complex in relation to the internal anatomy and localization of expressed genes and virions in the whitefly vector, which poses a major constraint to vegetable and fiber production in Israel and the USA. While many biological parameters are known for begomovirus transmission, nothing is known about vector proteins involved in the specific interactions between begomoviruses and their whitefly vectors. Identifying such proteins is expected to lead to the design of novel control methods that interfere with whitefly-mediated begomovirus transmission. The project objectives were to: 1) Perform gene expression analyses using microarrays to study the response of whiteflies (B, Q and A biotypes) to the acquisition of begomoviruses (Tomato yellow leaf curl (TYLCV) and Squash leaf curl (SLCV). 2) Construct a whitefly proteome from whole whiteflies and dissected organs after begomovirus acquisition. 3) Validate gene expression by q-RTPCR and sub-cellular localization of candidate ESTs identified in microarray and proteomic analyses. 4) Verify functionality of candidate ESTs using an RNAi approach, and to link these datasets to overall functional whitefly anatomical studies. During the first and second years biological experiments with TYLCV and SLCV acquisition and transmission were completed to verify the suitable parameters for sample collection for microarray experiments. The parameters were generally found to be similar to previously published results by our groups and others. Samples from whole whiteflies and midguts of the B, A and Q biotypes that acquired TYLCV and SLCV were collected in both the US and Israel and hybridized to B. tabaci microarray. The data we analyzed, candidate genes that respond to both viruses in the three tested biotypes were identified and their expression that included quantitative real-time PCR and co-localization was verified for HSP70 by the Israeli group. In addition, experiments were undertaken to employ in situ hybridization to localize several candidate genes (in progress) using an oligonucleotide probe to the primary endosymbiont as a positive control. A proteome and corresponding transcriptome to enable more effective protein identification of adult whiteflies was constructed by the US group. Further validation of the transmission route of begomoviruses, mainly SLCV and the involvement of the digestive and salivary systems was investigated (Cicero and Brown). Due to time and budget constraints the RNAi-mediated silencing objective to verify gene function was not accomplished as anticipated. HSP70, a strong candidate protein that showed over-expression after TYLCV and SLCV acquisition and retention by B. tabaci, and co-localization with TYLCV in the midgut, was further studies. Besides this protein, our joint research resulted in the identification of many intriguing candidate genes and proteins that will be followed up by additional experiments during our future research. To identify these proteins it was necessary to increase the number and breadth of whitefly ESTs substantially and so whitefly cDNAs from various libraries made during the project were sequenced (Sanger, 454). As a result, the proteome annotation (ID) was far more successful than in the initial attempt to identify proteins using Uniprot or translated insect ESTs from public databases. The extent of homology shared by insects in different orders was surprisingly low, underscoring the imperative need for genome and transcriptome sequencing of homopteran insects. Having increased the number of EST from the original usable 5500 generated several years ago to >600,000 (this project+NCBI data mining), we have identified about one fifth of the whitefly proteome using these new resources. Also we have created a database that links all identified whitefly proteins to the PAVEdb-ESTs in the database, resulting in a useful dataset to which additional ESTS will be added. We are optimistic about the prospect of linking the proteome ID results to the transcriptome database to enable our own and other labs the opportunity to functionally annotate not only genes and proteins involved in our area of interest (whitefly mediated transmission) but for the plethora of other functionalities that will emerge from mining and functionally annotating other key genes and gene families in whitefly metabolism, development, among others. This joint grant has resulted in the identification of numerous candidate proteins involved in begomovirus transmission by B. tabaci. A next major step will be to capitalize on validated genes/proteins to develop approaches to interfere with the virus transmission.

The objectives of this project were to develop procedures and models, based on neural networks, for quality sorting of agricultural produce. Two research teams, one in Purdue University and the other in Israel, coordinated their research efforts on different aspects of each objective utilizing both melons and tomatoes as case studies. At Purdue: An expert system was developed to measure variances in human grading. Data were acquired from eight sensors: vision, two firmness sensors (destructive and nondestructive), chlorophyll from fluorescence, color sensor, electronic sniffer for odor detection, refractometer and a scale (mass). Data were analyzed and provided input for five classification models. Chlorophyll from fluorescence was found to give the best estimation for ripeness stage while the combination of machine vision and firmness from impact performed best for quality sorting. A new algorithm was developed to estimate and minimize training size for supervised classification. A new criteria was established to choose a training set such that a recurrent auto-associative memory neural network is stabilized. Moreover, this method provides for rapid and accurate updating of the classifier over growing seasons, production environments and cultivars. Different classification approaches (parametric and non-parametric) for grading were examined. Statistical methods were found to be as accurate as neural networks in grading. Classification models by voting did not enhance the classification significantly. A hybrid model that incorporated heuristic rules and either a numerical classifier or neural network was found to be superior in classification accuracy with half the required processing of solely the numerical classifier or neural network. In Israel: A multi-sensing approach utilizing non-destructive sensors was developed. Shape, color, stem identification, surface defects and bruises were measured using a color image processing system. Flavor parameters (sugar, acidity, volatiles) and ripeness were measured using a near-infrared system and an electronic sniffer. Mechanical properties were measured using three sensors: drop impact, resonance frequency and cyclic deformation. Classification algorithms for quality sorting of fruit based on multi-sensory data were developed and implemented. The algorithms included a dynamic artificial neural network, a back propagation neural network and multiple linear regression. Results indicated that classification based on multiple sensors may be applied in real-time sorting and can improve overall classification. Advanced image processing algorithms were developed for shape determination, bruise and stem identification and general color and color homogeneity. An unsupervised method was developed to extract necessary vision features. The primary advantage of the algorithms developed is their ability to learn to determine the visual quality of almost any fruit or vegetable with no need for specific modification and no a-priori knowledge. Moreover, since there is no assumption as to the type of blemish to be characterized, the algorithm is capable of distinguishing between stems and bruises. This enables sorting of fruit without knowing the fruits' orientation. A new algorithm for on-line clustering of data was developed. The algorithm's adaptability is designed to overcome some of the difficulties encountered when incrementally clustering sparse data and preserves information even with memory constraints. Large quantities of data (many images) of high dimensionality (due to multiple sensors) and new information arriving incrementally (a function of the temporal dynamics of any natural process) can now be processed. Furhermore, since the learning is done on-line, it can be implemented in real-time. The methodology developed was tested to determine external quality of tomatoes based on visual information. An improved model for color sorting which is stable and does not require recalibration for each season was developed for color determination. Excellent classification results were obtained for both color and firmness classification. Results indicted that maturity classification can be obtained using a drop-impact and a vision sensor in order to predict the storability and marketing of harvested fruits. In conclusion: We have been able to define quantitatively the critical parameters in the quality sorting and grading of both fresh market cantaloupes and tomatoes. We have been able to accomplish this using nondestructive measurements and in a manner consistent with expert human grading and in accordance with market acceptance. This research constructed and used large databases of both commodities, for comparative evaluation and optimization of expert system, statistical and/or neural network models. The models developed in this research were successfully tested, and should be applicable to a wide range of other fruits and vegetables. These findings are valuable for the development of on-line grading and sorting of agricultural produce through the incorporation of multiple measurement inputs that rapidly define quality in an automated manner, and in a manner consistent with the human graders and inspectors.
