Résumé :

Purpose The purpose of this study is to discuss how enhancing the role of local institutions (LI) and incorporating indigenous knowledge (IK) in climate change adaptation planning can improve adoption and scaling success of climate-smart agriculture innovations. Design/methodology/approach A review of relevant literature from sub-Saharan Africa was used to answer the study research questions. Findings Embracing IK and LI in climate change adaptation projects can enhance adoption and scaling success of climate-smart agriculture innovations in smallholder farming. Such efforts will improve: information gathering and dissemination, mobilization of resources, establishment of useful networks with relevant stakeholders, capacity building farmers on various fronts and provision of leadership in climate adaptation programs. Practical implications Fully embracing IK and LI can improve the scaling of climate-smart innovations only if development partners recognize IK systems that are to be transformed and build on them instead of trying to replace them. Also, participatory approaches in scaling innovations will enhance input from rural people in climate change adaptation programs. Originality/value Development interventions aimed at taking proven effective climate-smart innovations to scale must, therefore, engage local communities and their indigenous institutions as active stakeholders in designing, planning and implementation of their climate adaptation programs.

Résumé :

Today, almost always Online Public Access Catalogues (OPACs) are the only way to access library collections, but practical experience shows that users have problems dealing with electronic catalogues. The author therefore recommends that any good OPAC needs an elaborated online help system. The present master thesis surveys implemented online help systems in German university OPACs and gives a critical discussion. Beyond the variety of help texts, the author also includes help systems like spell check, search filters for results and recommender. On one hand, the analysis is based on a function-related classification of those help systems and on the other, the introduction of the terms effectiveness and efficiency serve as parameters to determine the usefulness of a help system. As a result, the author presents basic principles for an efficient help system that are based on the findings of this master thesis.

Résumé :

This M. A. Thesis deals with the development of adaptive questionnaires for the user-centered evaluation of website usability and an appropriate web application for this purpose. In this matter, a classification scheme for six various website contexts is generated: E-Commerce, Entertainment, Social Software, Information, Homepages (organizational/personal) and E-Learning. For each category, specific usability criteria based on recent literature are identified. These will be the groundwork for the development of category-based 5-level Likert scale items of which the later questionnaires will be composed. The questions will be tested and evaluated by usability-experts and students to ensure their quality and usefulness. After that, a final test with end-users is done using the complete question set of each category to evaluate a corresponding website followed by the analysis of the results. In a final step, a prototype for the web application is developed which will build the basis for the upcoming implementation.

Texte intégral

Résumé :

FRBR is a conceptual model for the bibliographic universe and aims to simplify browsing in online library catalogues with special regard to users' needs. The data format still in use in the Austrian Library Network is MAB2. Bibliographic records are created according to the rules for alphabetic cataloguing in academic libraries. In 2009 Primo was implemented – a software which is capable of normalizing bibliographic records for front-end display. This Master Thesis wants to highlight the possibilities in Primo for metadata display in accordance with FRBR and the problems occurring in this regard, illustrated by bibliographic records describing Franz Kafka's "Der Process" ("The trial"). The analysis focuses on three aspects: the concept of "work", expressions as valid entities and aggregates respectively multipart monographs. A short introduction into the FRBR model is followed by the attempt to create an ideal FRBR tree for the different manifestations of Kafka's "The trial". Problematic aspects within the model itself are highlighted. Subsequently bibliographic records from the Austrian Cooperative Catalogue are analyzed in order to show the FRBR capability of MAB2 and beyond that to explain the FRBR key options in Primo. Some limitations of FRBRizing MAB2 in Primo have been made particularly apparent: The data in MAB2 records is not consistent enough to enable catalogue displays in accordance with FRBR. Moreover, the possibilities of clustering works and facets may improve browsing for library users, but not as FRBR would propose.

Résumé :

The report outlines research with blind and partially sighted people using electronic information services in real-life situations, and specifically how their experiences might inform the planning of these services in UK public libraries. Based upon a full literature review, a survey was conducted of blind and partially sighted people who have some experience of using electronic information services, suitable for, but not restricted to use in, public libraries. The methodology outlines the creation of two electronic survey formats, designed to be accessible and usable for blind and visually impaired people, and the related issues of delivery for the study sample. The data collected is included, and a full analysis of the findings is presented. Correlation was found with other wider surveys in the specific fields of blind and visually impaired people, and electronic information services. The report concludes that the visually impaired and especially blind people surveyed feel that libraries are out of touch with their needs relating to electronic information services, that there is correlation between users’ personal preferences and the usability of services, and that diverse and varying services act as a barrier to use. Evidence was also found to support the idea that computer access technologies aimed at blind and visually impaired people may attract very little use in libraries, without significant investment in staff training. A case is made for greater investigation of remote access to electronic services that can be accessed by blind people with their own equipment. This is felt to have usability benefits such as users’ familiarity with their own systems, and the reduction of unnecessary travel. It was also concluded that there is a need for specific consultation with people who are blind, separate from those who are partially sighted, and early involvement of both groups in testing of new services.

Résumé :

The ultimate goal of e-Governance is to reach the stage of seamless service delivery in one-stop e-Government. This raises the engineering issues of integration, reusability, maintenance, and interoperability of autonomous e-Government systems of government departments and agencies. Therefore, appropriate methodologies that consistently address the aforementioned engineering issues throughout clearly defined e-Government development phases are needed. This chapter provides the design and specification, of a framework that amalgamates features from maturity models, software engineering and Semantic Web domains for semantic-enabled development of e-Government systems. Firstly, the methods and techniques used for the planning, design, and implementation of e-Government systems worldwide are investigated; a critical analysis is carried out to identify their advantages and disadvantages, as well as their contribution towards addressing the aforementioned engineering issues. Secondly, the proposed framework is drawn and specified. Finally, support tools including a business process model, an alignment matrix of stages and phases of development, and a weighting matrix of the intensity of semantic activities at various phases of development is drawn and described.

Résumé :

The reliability of an elevator system in a smart city is of great importance. This chapter develops a conceptual framework for the design and development of an automated online condition monitoring system for elevators (AOCMSE) using IoT techniques to avoid failures. The elevators are powered by the traction motors. Therefore, by placing vibration sensors at various locations within the traction motor, the vibration data can be acquired and converted to 2D grayscale images. Then, maximum response-based directional texture pattern (MRDTP) can be applied to those images which are an advanced method of feature extraction. The feature vectors can also be reduced in dimension using principal component analysis (PCA) and then given to extreme learning machine (ELM) for the classification of the faults to five categories. Thus, the failure of elevators and the consequences can be prevented by sending this detected fault information to the maintenance team.

Résumé :

Due to the high maintenance cost of traditional online auction system, poor load balance ability and down problems occurring in the peak value of system access, this paper aims to propose a solution to transit from traditional online auction system to cloud computing to get higher work efficiency, lower expenditure and less energy cost. The GAE platform is used to deploy application of the overall framework of online auction system in cloud computing, including development environment as well as online auction system components, and software architecture. The online auction negotiation algorithms in cloud computing are also proposed. Based on these key technologies, the business processes of the online auction system in cloud computing is designed, including users' login system, starting an auction, bidding processes, online auction data storage, and logout system. The online auction system constructed on GAE platform with cloud computing resources and storage ability can reduce the pressure of terminal equipment, which is more robust than traditional online auction system facing users' changeable needs in the process of online auction.

Résumé :

Buildings lifecycle management is an area of great interest. Due this, the R&D is being promoting worldwide looking for new effective maintenance tools and methodologies. In this scenario there are two development lines whose convergence can bring great advances in this area: Asset Management (AM) and Building Information Modeling (BIM). BIM models are transforming the way buildings are conceived, designed, constructed and managed. But current use of BIM concentrates on preplanning, design, construction and integrated project delivery of buildings and facilities, rather than maintenance and building operation management. Asset Management tools, including Facilities Management (FM), and application frameworks provide the approach and required elements to get more efficiency and efficacy in the building lifecycle management. This chapter introduces the application of AM for building and how the development of BIM models is the key element to allow its effective implementation.

Résumé :

Modern universities thrive on the information gathered through well-managed information systems. The overall process of developing and maintaining Academic Information System (AIS) all within the university and without any external assistance is generally regarded as a mark of achievement. This chapter deals with various aspects of AIS such as requirements, development, testing, overall security, etc. Two major options, developing AIS from scratch and deploying a commercially available software solution, are discussed. Typical management strategies are suggested to combat possible resistance from users and to serve a wider-ranging user community in an effective manner. A strong case is made in favor of in-house development of AISs to reduce initial costs and maintenance expenditure. Importantly, the process of design, developing a functional prototype, and overall security aspects are presented in detail. Several recommendations are made to deal with various operational challenges through well-known practices.

Résumé :

Traditionally, the development of virtual environments has been tightly dependent on the programmer’s skills to manage the available toolkits and authoring systems. In such a scenario, the discussion of different design alternatives, future changes and maintenance, interoperability, and software reuse are all of them costly and quite difficult. In order to overcome this unsystematic and technology-driven process, conceptual modeling has to be included just before the implementation phase to provide a shared representation language that facilitates the communication among the different team members, including stakeholders, as well as the reuse and redesign for future requirements since conceptual models hide implementation details and constraints, and are cheaper and easier to produce than prototypes. As a first attempt to attain these aims, this chapter presents the basis of a constructional approach for the VE conceptual modeling through a set of complementary design views related to the VE components and functions. Moreover, we explore how these design issues might be addressed by hypermedia modeling techniques, given the similarities between these two kinds of interactive systems and the maturity reached in hypermedia development.

Résumé :

For the last few years, model-driven architecture, aspect-oriented software development and Web service engineering have become widely accepted alternatives for tackling the design and building of complex distributed applications; however, each of them addresses the principle of separation of concerns from their own perspective. When combined appropriately, both model-driven and aspect-oriented software development complement each other to develop high-quality Web service-based systems, maintaining non-functional properties separate from models to code. This chapter provides a methodology that integrates non-functional properties into Web service model-driven development, increasing the systems’ modularity and thus reducing implementation and maintenance costs.

Résumé :

The importance of maintenance has increased, as high productivity and quality can be achieved by means of well-developed and organised maintenance strategies. However, this assumes that maintenance is controlled in such a way that equipment is stopped for maintenance via a systematic schedule. With the recent advances in technology many methodologies, tools, techniques and strategies have been developed and tested. Unfortunately, the majority of organisations are constrained by certain barriers with the resulting loss of major benefits. These are usually classified as Small and Medium Sized Enterprises (SMEs). Based upon our data analysis a new maintenance methodology, the Advanced Integrated Maintenance Management System (AIMMS) is developed. To enable the implementation, monitoring and evaluation of AIMMS a computerised system — Maintenance Management (MainMan) — was developed and implemented within several case study companies. This paper examines the implementation process within one of these companies. The results indicate that AIMMS supports strategic maintenance decisions, and helps to increase equipment effectiveness through prioritising equipment criticality and focusing on specific resources that will maximise gains based upon a return on investment.

Résumé :

A detailed & proper understanding of the main components that comprise a Steam Surface Condenser is absolutely essential when designing an effective maintenance regime. This Paper provides a breakdown for each of the main components, including typical ancillary items, which should be incorporated into visual inspections, and routine testing, when developing an effective maintenance regime for Steam Surface Condensers. Topics cover recommended inspection criteria for the main and ancillary components as well as proposed testing methods. Examples of known component failure modes, suggested repairs, replacements, modifications & upgrades are also included for reference. Implementation of an effective maintenance regime can help to ensure design performance is maintained. Often, it can even lead to improvements in unit availability and overall long term reliability; which in turn can result in tangible reductions in operating costs.

Résumé :

<p>The application of Building Information Modeling is based on the definition of basic classifications to create a clear data structure in which specific parameters can be defined. In building construction, such basic classifications are already in use. However, there are no standardized definitions of the data basis concerning the transport infrastructure stock. Therefore, a data structure is needed to capture all planes of design, construction, and maintenance. In the course of this work, a BIM data structure was developed together with Austrian infrastructure owners –Austrian Federal Railways and Highways Agency. Within the research group, the University of Applied Sciences “FH Campus Wien”, Vienna, was responsible for the topic of bridges and bridge maintenance. A consistent data structure is the basis for BIM implementation in infrastructure engineering. The potentials range from the use of BIM models for static calculations to their application in maintenance management.</p>

Résumé :

Small Modular Reactors (SMRs) under design and development today are working to crystallize the measurements that must be made to control the reactor and monitor its safety. Traditionally, temperature, pressure, level, flow, and neutron flux are measured in conventional nuclear reactors for operation and control and to protect against equipment and process deviations that can affect safety. In most current SMR designs, essentially the same process variables may have to be measured; especially primary coolant flow depending on whether the core cooling and heat transfer results from natural circulation or forced flow. The flow can be measured directly or inferred from other measurements or estimated through empirical or physical modeling. The conventional sensors that are qualified for nuclear services and are currently used in nuclear power plants may or may not be suitable for SMRs. It all depends on the size and qualification requirements, installation details, static and dynamic performance specifications, wiring details, and sensor life expectancy. This paper will explore the possibilities that exist for SMRs to use today’s sensors and any need for new sensor designs. In addition, the paper will identify new means for automated monitoring of instrumentation and control (I&C) sensor performance in SMRs. In particular, the existing array of online calibration monitoring techniques and in-situ response time measurement methods will be evaluated for implementation in SMRs. This is important at this early stage as SMRs can easily build provisions in their mechanical, electrical, and I&C designs to accommodate online and automated I&C maintenance. For example, it is envisioned that SMRs will not be performing periodic sensor calibrations using classical hands-on procedures. Rather, SMRs are expected to be equipped with new technologies to verify the I&C performance automatically and flag the sensors and systems to be calibrated, response time tested, repaired, or replaced. The paper will explore these possibilities and will report on a current R&D project that is underway at AMS with funding from the U.S. Department of Energy (DOE) with the goal to adapt the existing online monitoring (OLM) technologies for implementation in SMRs. The existing OLM technologies have been used by AMS in commercial nuclear power plants and research reactors for monitoring of I&C equipment performance including calibration, response time, detection of sensing line blockages, and to distinguish whether a signal anomaly is due to cables/connectors, electromagnetic interference, an end device being a sensor or a pump, other rotating equipment, etc.

Résumé :

North American turnout and special trackwork design has evolved in an operating environment in which axle loads have increased significantly but operating speeds have remained modest. Consequently, while trackwork components have become much more robust, turnout geometries and overall system design has remained essentially static for many decades. Implementation of high speed rail (“HSR”) in North America will necessitate a radically different approach to turnout engineering. While there is much to be learned from European and Asian experience with high speed, it is anticipated that vehicle designs and mixed freight access will result in much greater axle loads. The combination of operating speed and loading will present unique challenges. Critical design elements for North America’s new generation of HSR turnouts will include: a) Compound geometries to optimize ride quality and safety while keeping overall lengths within manageable limits. b) Fastening and horizontal support systems to withstand high dynamic lateral loads. c) Dampening systems to attenuate high frequency vibration. d) Detailing such as rail seat canting and kinematic gauge optimization to enhance ride quality and increase component life. e) High modulus vertical support systems. f) Drive and locking systems specifically tailored to long HSR layouts. Regulations governing the layout and maintenance tolerances of North American turnouts will also have to be re-examined with the advent of high speed rail. Complex geometries and rapid transient loading will render the conventional approach of limiting speeds based on calculated imbalance ineffective. Accurate and rational assessment of operating safety will demand the application of dynamic numeric modeling to the entire vehicle / turnout system.

Résumé :

A paper will be presented describing the design and development of the Gas Turbine Local Controller replacement used on the Magnetic Minesweeping Gas Turbine Generator (MMGTG) on the US Navy MCM-1 Class of ships. The advent of processor based controllers including PLCs has provided a low cost alternative for control system upgrades when faced with increasing maintenance costs and obsolescence issues of analog and hard relay logic control systems. The replacement controller is a Programmable Logic Controller (PLC) based system linked to a flat panel display and a supervisory control system. A MMGTG during pulsing operations applies a severe load transient cycle to the gas turbine for the fuel control to meet in a stable and safe manner. The algorithms which employ an adaptive Proportional Integral Derivative (PID) loop control structure with internal limiting constraints based on engine state are used to manage these transients, power turbine entry temperature and a wide range of steady state operation. The controller includes logic for alarming, start/stop and automatic shutdown. The design of the hardwired automatic shutdown logic integrated to the PLC will be presented. The control system design will be described in terms of its integration to a supervisory network, local control functionality and shipboard considerations. The Human Machine Interface screens of the flat panel display and their design are also considered.

Résumé :

Abstract The paper presents a complex approach based on the experience of the authors of this article for creating and maintaining integrated asset models (IAM) and implementing a digital data management platform. Problems of using IAM for the operational management of field development and production are that the data is not accurate, the measurements are spaced in time, and there is not enough data to understand the physical phenomena taking place. The complex approach is that to provide integrated asset models with high-quality data, it is necessary to build new processes, create new specialties and competencies, the key success factor is the combination of the experience of Customer (oil company), Internal oil-related service of Customer (geological and geophysical research), External contractor of oil-related service (the combination of experience in geological and geophysical research, experience in integrated asset modeling and operational support for field development using integrated asset modeling tools and digitalization of data management). The best way to implement the approach of creating joint Integrated Team of External and Internal oilfield service Contractors in the form of Complex Service Engineering Center, the task for which which was the organization of a cyber-physical system for collecting field data, verifying data, identifying problem areas in data, defining approaches to eliminating problem areas using tools of automation tools for working with data, the flexible management of well testing and survey programs, the operational formation of well testing and survey design for non-standard situations. Particular attention in this complex approach is paid to working with initial field data, this article provides a general scheme for verifying the various parameters of well operation and an example of its use for flow rates, as well as examples of the quality analysis of reservoir pressures based on the use of a two-dimensional one-phase proxy reservoir model and the quality analysis of GOR for a well. Based on the developed complex approach, the paper provides examples of strategic and operational problems for a field - the assessment of optimal production for a field and the assessment of oil shortfalls for a well, respectively.

Résumé :

The manufacturers are competing against each other based on their development ability. A manufacturer who wants to do better than others must emphasize its ability of product development. The resources that product development relies on are more distributed than ever along with the varying of the global design environment. So more and more resources outside of enterprises are needed during the product design process. The platform supporting the product modern design under the circumstance of distributed resources will meet the requirement of the enterprise’s product design and development under such conditions. The platform will also simplify the implementation on the integral of the IT support system for design resources outside of enterprises. In this paper the characteristics and supporting technologies of product design platform, which supporting the distributed design resource circumstance and centering on the enterprise, are studied. The building method of the platform is presented and a prototype of the product design platform is developed. Three subsystems are included in the platform. They are the product requirements analysis system, the product design planning system and the knowledge management system. Many design tasks can be supported on the platform, such as product requirement analysis, concept design, detail design, experiment, and maintenance knowledge acquirement. The distributing, implementing, tracking and managing of product lifecycle tasks can also be supported on the platform. The distributed design resources could be sealed as application components to provide design services. Design work flow model and knowledge flow model are built and controlled through the FIPER software. The design knowledge is managed based on the ontology theory. The virtual prototype of a complex product can be built and run more easily with the design platform. The process of building a virtual prototype could be described simply as following. Firstly the distributed models are sealed as application components. Then the components are published in the FIPER environment. Finally, the virtual prototype is built in the form of design work flow model in which the distributed components are integrated. To simulate the coupling of multi-discipline behaviors in a complex product design, the coupling formula is proposed to express the relations of different discipline behaviors. Based on the coupling formula, the coupling simulation can be run on the platform. Finally, a lifecycle performance prototype of an internal combustion engine is developed through the platform to verify the platform’s functions.

Résumé :

This special report discusses the outcomes of a September 2019 workshop intended to identify barriers to the consideration and implementation of natural and nature-based features (NNBF) in US Army Corps of Engineers (USACE) civil works projects. A total of 23 participants representing seven USACE districts, the US Army Engineer Research and Development Center (ERDC), and the University of California–Santa Cruz met at USACE’s South Atlantic Division Headquarters in Atlanta, Georgia, to discuss how to facilitate the implementation of NNBF into USACE project planning for wetlands and reefs using six categories: (1) site characterization, (2) engineering and design analysis, (3) life-cycle analysis, (4) economic analysis, (5) construction analysis, (6) and operation and maintenance (and monitoring). The workshop identified seven future directions in wetland and reef NNBF research and development: • Synthesize existing literature and analysis of existing projects to better define failure modes. • Determine trigger points that lead to loss of feature function. • Identify performance factors with respect to coastal storm risk management (CSRM) performance as well as ecological performance. • Focus additional research into cobenefits of NNBF. • Quantify the economic life-cycle costs of a project. • Improve technology transfer with regards to NNBF research and topics.

Résumé :

To improve traffic performance and safety, the ability to measure traffic accurately and effectively, including motorists and other vulnerable road users, at road intersections is needed. A past study conducted by the Center for Road Safety has demonstrated that it is feasible to detect and track various types of road users using a LiDAR-based system called TScan. This project aimed to progress towards a real-world implementation of TScan by building two trailer-based prototypes with full end-user documentation. The previously developed detection and tracking algorithms have been modified and converted from the research code to its implementational version written in the C++ programming language. Two trailer-based TScan units have been built. The design of the prototype was iterated multiple times to account for component placement, ease of maintenance, etc. The expansion of the TScan system from a one single-sensor unit to multiple units with multiple LiDAR sensors necessitated transforming all the measurements into a common spatial and temporal reference frame. Engineering applications for performing traffic counts, analyzing speeds at intersections, and visualizing pedestrian presence data were developed. The limitations of the existing SSAM for traffic conflicts analysis with computer simulation prompted the research team to develop and implement their own traffic conflicts detection and analysis technique that is applicable to real-world data. Efficient use of the development system requires proper training of its end users. An INDOT-CRS collaborative process was developed and its execution planned to gradually transfer the two TScan prototypes to INDOT’s full control. This period will be also an opportunity for collecting feedback from the end user and making limited modifications to the system and documentation as needed.
