Abstract (sommario):

Service-oriented learning environments are the new paradigm for interoperability of learning management systems. They support a wider range of needs by integrating existing and emergent services, leading to an entirely new architectural design for such systems. The engineering life-cycle of resources and services can be enhanced and integrated in current and future virtual learning environments. This work defines a services-enhanced learning architecture and describes two levels of integration carried out to author, deploy and enact learning services from open web-based interaction protocols and semantic web service descriptions.

Abstract (sommario):

The magnitude of today’s highway maintenance challenge, the impact of research on maintenance, basic objectives that should drive a maintenance program, and the progress made in meeting them over the last 4 decades are discussed. Highway maintenance should include the objectives of providing a consistently safe, comfortable, and efficient travel way for highway users and a safe environment for maintenance crews; providing optimum service life; maintaining as-built capacity and reliability; inviting, supporting, and using research and innovation; and performing with professionalism, competence, and diligence. Some of the challenges in meeting these objectives today are accelerating rates of deterioration, limited time available to work, complex interchanges and crowded rights-of-way, environmental restrictions, a litigious society, and public skepticism about all government functions. Three categories of responses are technologies, policies, and professionalism. A significant array of new, innovative tools and other products of research are making maintenance technology more effective. Maintenance managers need to be activists in promoting progressive policies in providing as-built capacity while performing maintenance and repair work and in procuring products and services. Maintenance policies should include recognition of user costs, use of performance specifications, fabrication of off-site repair components, design of repairable highway systems, use of corrosion-resistant materials, privatization of segments of the maintenance program, and establishment of an international maintenance technology reference program. Individual professionals must embrace continuing education, environmental sensitivity, community service, research and development, innovative management, and societal and political responsibilities.

Abstract (sommario):

The paper is aimed to the methodology for estimation of service life of mechanical engineering components in the case of elastic-plastic contact of surfaces. Well-known calculation methods depending on physics, theory of probability, the analysis of friction pair’ shape and fit include a number of parameters that are difficult or even impossible to be technologically controlled in the manufacturing of mechanical engineering components. The new approach for wear rate estimation using surface texture parameters as well as physical-mechanical properties and geometric parameters of components is proposed. The theoretical part of the calculations is based on the 3D surface texture principles, the basics of material fatigue theory, the theory of elasticity and the contact mechanics of surfaces. It is possible to calculate the service time of the machine, but the process of running-in of the components is relatively short (less than 5%), therefore, the service time is mainly determined by a normal operating period, which also was used to evaluate this period. The calculated input parameters are technologically and metrologically available and new method for calculating the service time can be used in the design process of the equipment. The results of approbation of the method for estimation service time of mechanical engineering, which prove the applicability of mentioned method, are offered as well.

Abstract (sommario):

ABSTRACTThe service life of aircraft structure includes the fatigue life and calendar life. The Aircraft Structural Life Envelop (ASLE) is a safe and reliable life scope of aircraft structures in service. The specific steps to establish the ASLE are developed, and a residual life prediction method for aircraft structure under service environments is established by combining the ASLE with the Miner theory. Furthermore, a service life extension method of aircraft structure is proposed based on a scope extension of the ASLE, including methods based on reliability analysis and structural repair. Finally, an application example of the ASLE is presented.

Abstract (sommario):

Purpose – Strategic trends towards service operations have been widely reported in the recent literature, but organisational capabilities to support such service-centred strategies are less well understood. The purpose of this paper is to identify key organisational issues in managing complex engineering service operations throughout the lifecycle. Design/methodology/approach – Using instruments developed from the product lifecycle management technologies and the network configuration concept, key organisational issues for engineering service operations were identified through case studies focusing on complex engineering products and services systems across a variety of industrial sectors. Findings – The case studies demonstrated different organisational features and strategic priorities of engineering service operations along the whole lifecycle. A generic trend has been observed for engineering systems to move from being design, development and manufacturing focused to embracing support and end-of-life recycling matters. Originality/value – This paper provides an overall framework for integrating key organisational issues in engineering service operations. It contributes to the service literature by highlighting the need of developing appropriate organisational capabilities to support service-centred strategies with engineering cases. It also provides guidance for companies to manage their engineering network operations throughout the whole lifecycle of complex products and services systems.

Abstract (sommario):

Information security is a key challenge in the Cloud because the data will be virtualized across different host machines, hosted on the Web. Cloud provides a channel to the service or platform in which it operates. However, the owners of data will be worried because their data and software are not under their control. In addition, the data owner may not recognize where data is geographically located at any particular time. So there is still a question mark over how data will be more secure if the owner does not control its data and software. Indeed, due to shortage of control over the Cloud infrastructure, use of ad-hoc security tools is not sufficient to protect the data in the Cloud; this paper discusses this security. Furthermore, a vision and strategy is proposed to mitigate or avoid the security threats in the Cloud. This broad vision is based on software engineering principles to secure the Cloud applications and services. In this vision, security is built into all phases of Service Development Life Cycle (SDLC), Platform Development Life Cycle (PDLC) or Infrastructure Development Life Cycle (IDLC).

Abstract (sommario):

In the analysis on whole structural life-cycle, there are two important factors to need to be considered. One is the determination of design service life of structure, and another is design of structure based on service life. After analyzing deeply the influence factors of life-time index, it can be found that the design service life of structure not only depends on technology level, functional requirement and economic cost factors of structures, but also relate with the specific environmental conditions, using conditions and maintenance conditions of structures. So that, an analysis method of determined design service life of structure is given in this paper. For design of structure on service life, from the view of whole structural life-cycle, a probability reliability-based analysis method of structural service life design and re-design is proposed in this paper. By updating constantly design parameters, the correctness of predicted service life is improved gradually.

Abstract (sommario):

Selected results and initiatives in modern asphalt pavement research for increasing service life of asphalt pavements under the aspect of sustainability and multifunctional use of roads are summarized. Focus lies on innovative approaches and own experience, jointly elaborated during the last decades within the road engineering/sealing components lab at Empa and both the highway/railways engineering and building materials group at KTH. This includes material concepts and design as well as pavement system and construction aspects from an experimental and modelling point of view. It includes also the application of powerful experimental and computational tools, such as Atomic-Force-Microscopy (AFM), X-Ray-Computer-Tomography (CT), Digital-Imaging-Correlation (DIC) and Discrete-Element-Method (DEM). As for materials, recycling issues and the use of Phase-Change-Materials (PCM) or metallic ingredients for inductive thermal crack healing are addressed. In order to remind that material design must also account for the workability during the process of compaction, the new Compaction-Flow-Test (CFT) developed at KTH is shortly presented. Innovative ideas for structural material composition are also mentioned, such as “artificial aggregates” or “additive manufacturing”, being aware that there is still a long way to go. Regarding pavement systems, ideas for multifunctional road applications are proposed. Focus is also put on special issues, such as construction joints.

Abstract (sommario):

Many petroleum companies have been using a tool developed by MPC for evaluating materials operating in the creep range. This method has now been recognized for inclusion in API RP579 on fitness-for-service. This paper reports on the method and explains the materials properties used therein. The MPC Omega method concentrates on the application of estimates of performance of materials at low design level stresses. The database upon which the materials properties are based was acquired by testing service exposed and softened steels and minimizing environmental effects. Use of the MPC properties in some cases could increase allowable stresses. However, the great advantage of the method is its capability as a tool for predicting strains, benchmarking materials, incorporation into finite element analysis, developing sensible testing strategies, and dealing with realistic stress situations.

Abstract (sommario):

The problem being reviewed in this article is quite complex and represents a combination of economic, technical, organizational, managerial relations in the management of the engineering systems of the real estate objects that arise in the process of forming a new technological paradigm in the context of growth of the digital economy. The article demonstrates that service activities cover a significant area of social relations associated with development, production and provisions of various types of services including the field of real estate. The study focuses on life cycle contracts for energy supply and it is shown that they are an integral part of the engineering systems management processes. The thesis is given that the service becomes an integral part of the good and the good becomes an integral part of the service. It is demonstrated that operation of the real estate objects including various intelligent buildings consists of various types of services which in one form or another are services by their nature – the services for maintaining the object in operative condition, the services for supplying the object with various resources, the services for maintaining the engineering systems of the object etc. It is shown the relationship between the processes of the real estate objects management and the processes related to the services actives. It is proposed to use the approaches of the systems engineering and the complex engineering in order to solve the tasks related to the management of the engineering systems.

Abstract (sommario):

The aim of this work is to study and model creep damage accumulation for remaining safe working life estimation of tube material used in petroleum industry plants operated at a high temperature for long time beyond the design life. Material constants and other data required for life estimation were extracted from the output results of real accelerated creep rupture tests conducted at three test temperatures (700, 725, and 750(oC and at three constant stress applications (120, 130, and 140 MPa). Also, a time-temperature parameter method (Larson-Miller Method) was modified to be applied based on the results of the accelerated creep rupture tests to build life predicted master curve for austenitic stainless steel type 321H. It is found that creep rupture time for stainless steel alloy decreases as temperature or stress increase. Also, it distinguished from the creep curves for the serviced stainless steel alloy, that the onset of tertiary creep stage starts early (about 50% of creep curve), this reflects the reduction in creep strength of the alloy as a result of the degradation in alloy properties that take place during the service life. It is also found that the estimated remaining working life for the serviced tube samples made from austenitic stainless steel type 321H is about (54703 hr) based on the calculated stress level (40 MPa) and service temperature 570 oC. The difference between the estimated remaining life and the experimental creep test life is due to the differences between the applied stresses, where higher level of stresses in the experimental creep testes are used to accelerate failure of specimens. The application for the result of this work can be the petroleum industries that where heaters tubes serviced at such industry need to be estimated for the remaining life after the design life expire.

Abstract (sommario):

In practical engineering design service life of glass fiber reinforced plastics (GRP) pipes have different requirements. The current specification for different engineering structure design life design only considers the change of variable load. The material properties of GRP pipes can be varied with the service life, which must be considered in the design. Through the analysis of the existing standard design method and principle, the double logarithmic linear extrapolation further promotion, and combine the reduction coefficient method, a simplified design method for GRP pipes of different design service life, which has strong reference significance and application value.

Abstract (sommario):

AbstractChloride ingress induced depassivation of reinforcing steel leading to corrosion is a major durability concern for concrete structures. The influence of the presence of cracks commonly occurring in concrete structures on chloride ingress should be accounted to improve the accuracy of service life predictions. This study investigates the depassivation probability of the reinforcement in both cracked and uncracked concrete using both analytical and 1D numerical models. The probabilistic service life prediction is realized using the Monte Carlo simulation to incorporate the uncertainty and variability in the input variables. For uncracked concrete the result of the numerical model agreed well with the fib chloride model. For cracked concrete, the numerical simulation suggests that the optimal engineering approach to account for cracks in a service life analysis is the adaptation of crack depth. Although, the approach could lead to an overestimation of chloride concentration because the 1D numerical simulation did not consider lateral diffusion in cracked concrete.

Abstract (sommario):

The remaining service life of reinforced stone arch bridges is of great concern to management and conservation units. It is also the scientific basis for decision to next reinforced maintenance or rebuild. The concept of time-dependent reliability is introduced. Accoding to the most common section enlargement reinforcement method, the load and resistance of the structures are analyzed. The analysis methods and steps of life prediction are proposed, and the remaining service life is obtained. Based on above methods, an engineering example is given, the service life forecast calculation of reinforced stone arch bridges is discussed.
