Abstract:
We consider two loosely coupled schemes for the solution of the fluid–structure interaction problem in the presence of large added mass effect. In particular, we introduce the Robin–Robin and Robin–Neumann explicit schemes where suitable interface conditions of Robin type are used. For the estimate of interface Robin parameters which guarantee stability of the numerical solution, we propose a new strategy based on the optimization of the reduction factor of the corresponding strongly coupled (implicit) scheme, by means of the optimized Schwarz method. To check the suitability of our proposals,

Abstract:
Accurate positioning and mapping are significant for autonomous systems with navigation requirements. In this paper, a coarse-to-fine loosely-coupled (LC) LiDAR-inertial odometry (LC-LIO) that could explore the complementariness of LiDAR and inertial measurement unit (IMU) was proposed for the real-time and accurate pose estimation of a ground vehicle in urban environments. Different from the existing tightly-coupled (TC) LiDAR-inertial fusion schemes which directly use all the considered ranges and inertial measurements to optimize the vehicle pose, the method proposed in this paper performs

Abstract:
To achieve the security inte-gration of 3G and WAPI based WLAN, a USIM based certificate distribution protocol is proposed. Two security integration schemes, i.e, loosely coupled and tightly coupled, are presented, which unify user management of 3G security architecture and WAPI, and realize WAPI based network access for 3G subscribers and identity privacy protection. The entity authentication and anonymity of the certificate distribution protocol is analyzed in CK model, and the results show that the protocol is provably secure.

An efficient artificial compressibility algorithm is developed for solving the three-dimensional Reynolds-averaged Navier-Stokes equations in conjunction with the low-Reynolds number k-ω turbulence model (Wilcox, 1994). Two second-order accurate central-differencing schemes, with scalar and matrix-valued artificial dissipation, respectively, and a third-order accurate flux-difference splitting upwind scheme are implemented for discretizing the convective terms. The discrete equations are integrated in time using a Runge-Kutta algorithm enhanced with local time stepping, implicit residual smoot

The current upheaval in the electricity sector demands distributed generation schemes that take into account individually configured energy units and new grid structures. At the same time, this change is heading for a paradigm shift in controlling these energy resources within the grid. Pro-active scheduling of active power within a (from a controlling perspective) loosely coupled group of distributed energy resources demands for distributed planning and optimization methods that take into account the individual feasible region in local search spaces modeled by surrogate models.

Abstract:
This paper theoretically derives the equivalence conditions for the loosely and tightly coupled GNSS/INS integration algorithms. Firstly, the equivalence is proved when using single epoch GNSS measurements, which means the GNSS processor provides standalone solution. Then, the equivalence proof is further extended for the filtering solutions, which are usually applied for differential GNSS and precise point positioning. Based on these, different state and measurement models for GNSS/INS integration navigation are summarized, and natural differences among these models are discussed. This indica

Abstract:
Database management systems (DBMS) are becoming part of environments composed of large-scale distributed heterogeneous and networks of autonomous, loosely coupled components. In particular, federated database management systems (FDBMS) can be seen as networks that integrate a number of pre-existing autonomous DBMS which can be homogeneous or heterogeneous. They can use different underlying data models, data definition and manipulation facilities, transaction management, and concurrency control mechanisms. DBMS in the federation can be integrated by a mediator providing a unified view of data: a global schema, a global query language, a global catalogue, and a global transaction manager. The underlying transaction model considers, in general, a set of transactions synchronized by a global transaction. Synchronization is achieved using protocols such as the Two-Phase Commit protocol. FDBMS applications are built upon this global environment, and they interact with the mediator to execute global database operations (i.e., operations that can concern various DBMS in the federation).

Abstract:
During the last two decades, many enterprises have put business processes in the focus of their organizational strategies both for internal and collaborative business activities. Business process models provide the IT department with a semiformal, business-driven requirements basis for implementing business strategy into information systems (Scheer, 1999). However, despite notable progress in integration technologies such as workflow management systems (WMS) and enterprise application integration (EAI) systems, executing enterprise applications along a business process has remained the challenge of any universal business process management (BPM) approach. The most recent technology paradigm of service-oriented architecture (SOA) is expected to accomplish seamless and flexible business process automation (Krafzig, Banke, & Slama, 2005). The vision of loosely coupled services, that execute business activities across heterogeneous, distributed software systems via the Internet, captivates by the extent of flexibility and responsiveness given to business management. Thus, service-oriented computing represents more than a concept of software engineering. It is rather considered to be the ultimate driver for a complete business reformation, finally bridging the gap between business strategy and technological infrastructure. Beyond these visionary perspectives, the effects of service-orientation on BPM methods and techniques will be manifold and challenging both for research and practice.

Abstract:
As a term used to denote the ability of defence systems to collaborate, interoperability has emerged as one of the most important capacities of information systems, during the last 30 years. Being important at organizational, process and semantic levels, interoperability soon became a key characteristic of information systems and services, both in the private and public sector. As a crucial prerequisite for automated process execution leading to “one-stop” electronic services and promising dramatic increase in productivity for enterprises of any size, interoperability has been systematically sought after, since the dawn of the 21st century: standardization frameworks, guidelines at enterprise level, data schemas and techniques to tackle the problem of non-communicating systems or organisations started to appear. In parallel, most international software, hardware and service vendors created their own strategies for achieving the goal of open, collaborative, loosely coupled systems and components. This chapter goes beyond the presentation of the main milestones in this fascinating quest for collaboration between people, systems and information: it attempts to describe how this new interdisciplinary research area can transform into a vibrant scientific domain, by applying the necessary method and tools. To achieve that, the chapter presents the ingredients of this new domain, proposes its needed formal and systematic tools, explores its relation with neighbouring scientific domains and finally prescribes the next steps for achieving the thrilling goal of laying the foundations of a new science.

Abstract The inertia projection schemes used in the existing recursive methods for the dynamic analysis of flexible multibody systems lead to dense coefficient matrices in the acceleration equations. Consequently, there is a strong dynamic coupling between the joint and modal coordinates. When the number of modal degrees of freedom increases, the size of the coefficient matrix in the acceleration equations becomes large and consequently the use of these recursive methods for solving the joint and modal accelerations becomes less efficient.

Abstract To tackle coupled problems between smooth multibody systems and particle dampers, co-simulation between two general-purpose multibody codes is carried out, where the coupled system is decomposed by the force/displacement technique, and integrated by a loose coupling scheme or a tight one with iterative process. The stability properties of the coupling schemes are discussed using a two-mass oscillator, and it follows that the tight coupling scheme is more stable than the loose one, as expected. Besides, results also denote that the stability is influenced by the parameters of the integ
