Discovering expert drivers is highly important for a broad range of location based services, but this issue is largely untouched in previous trajectory mining and search studies. In this paper, we study the problem of trajectory data driven expert driver discovery. It aims to find out top-k expert drivers about a region of interest, based on the understanding of their historical trajectories. To this end, we first investigate the construction of reference system, which collectively describes exemplar routes among important junctions, so that the driving behaviors embedded in each trajectory can be evaluated. To discover expert drivers accurately, a novel tf-idf concept based measure is proposed afterwards, such that the rationality of their trajectories are not only precisely evaluated by the match to reference system, but also properly aggregated for modelling expert drivers. Extensive experimental evaluation using real trajectory datasets demonstrates the effectiveness and efficiency of our proposed solutions. © 2018 IEEE.

In this paper, we will do some researches on the relationship between action sequence and system efficiency in multi-agent system. Usually, when an agent gets a task, it will calculate all the feasible action sequences and choose the best one whether the task has used to appeared in this system before. It wastes a lot of time on re-calculating and recomparing. So we propose solution sharing mechanism to make all the agents share the same solution space which keeps the current optimal plan for tasks. After achieved new tasks, each agent will have only one calculation and comparison, and then choose the better current action sequence. The reduction of time and better action sequence will improve the efficiency of multi-agent system. © The Authors.

Recognition of activities in an unobtrusive manner has attracted the attention of context aware systems, which provide end users with services based on everyday activities that are recognised without infringing the privacy of the end user. Current work has generally focused on applying a range of traditional classification and semantic reasoning based techniques in order to recognise these activities. However, the ability to recognise unexpected actions while the activity is being conducted remains a challenge. In this paper, we present an approach that is able to recognise activities regardless of the order of tasks/actions used to perform the activity. The proposed recognition framework extends an existing activity recognition approach by deploying a frequent pattern mining technique to find patterns among different streams of captured sensor events in order to increase the adaptive learning of the proposed recognition approach. © 2015 ACM.

In this paper, we do research based on the multi-agent system (MAS) with learning mechanism. Making use of agent perception ability, we enable the agents to collect environment information and store it into the shared knowledge base. According to the content of knowledge base, MAS with learning ability will optimize the independence service process;decrease the choosing process time of agent behavior. At last, we set the upper limit of knowledge base capacity to resolve the problem of knowledge base retrieval which will cause time increasing during the system running. It will proof that, the MAS with learning mechanism has a better efficiency. © 2011 IEEE.

Vehicular Ad-hoc networks（VANETs） are kinds of mobile Ad-hoc networks（MANETs）, which consist of mobile vehicles with on-board units（OBUs） and roadside units（RSUs）. With the rapid development of computation and communication technologies, peripheral or incremental changes in VANETs evolve into a revolution in process. Cloud computing as a solution has been deployed to satisfy vehicles in VANETs which are expected to require resources（such as computing, storage and networking）. Recently, with special requirements of mobility, location awareness, and low latency, there has been growing interest in research into the role of fog computing in VANETs. The merging of fog computing with VANETs opens an area of possibilities for applications and services on the edge of the cloud computing. Fog computing deploys highly virtualized computing and communication facilities at the proximity of mobile vehicles in VANET. Mobile vehicles in VANET can also demand services of low-latency and short-distance local connections via fog computing. This paper presents the current state of the research and future perspectives of fog computing in VANETs. Moreover, we discuss the characteristics of fog computing and services based on fog computing platform provided for VANETs. In this paper, some opportunities for challenges and issues are mentioned, related techniques that need to be considered have been discussed in the context of fog computing in VANETs. Finally, we discuss about research directions of potential future work for fog computing in VANETs. Within this article, readers can have a more thorough understanding of fog computing for VANETs and the trends in this domain.

The necessity of achieving an effective balance between minimizing the losses associated with restricting human mobility and ensuring hospital capacity has gained significant attention in the aftermath of COVID-19. Reinforcement learning (RL)-based strategies for human mobility management have recently advanced in addressing the dynamic evolution of cities and epidemics;however, they still face challenges in achieving coordinated control at the township level and adapting to cities of varying scales. To address the above issues, we propose a multi-agent RL approach that achieves Pareto optimality in managing hospital capacity and human mobility (H2-MARL), applicable across cities of different scales. We first develop a township-level infection model with online-updatable parameters to simulate disease transmission and construct a city-wide dynamic spatiotemporal epidemic simulator. On this basis, H2-MARL is designed to treat each division as an agent, with a trade-off dual-objective reward function formulated and an experience replay buffer enriched with expert knowledge built. To evaluate the effectiveness of the model, we construct a township-level human mobility dataset containing over one billion records from four representative cities of varying scales. Extensive experiments demonstrate that H2-MARL has the optimal dual-objective trade-off capability, which can minimize hospital capacity strain while minimizing human mobility restriction loss. Meanwhile, the applicability of the proposed model to epidemic control in cities of varying scales is verified, which showcases its feasibility and versatility in practical applications.

Component-based software development is becoming a discipline in software engineering community, but it still immature in enterprise application development. OSGi gives some insights for component-based development (CBD). By proposing an ideal component model for enterprise applications, we analyze the performance of OSGi against such a model. The result shows that OSGi is still lack of some advanced component features for CBD, although it provides a modular solution superior to plain Java. The result also contributes both to the decision making for the software developers who want to select the OSGi component technology and to the improvements to be made to OSGi. © 2010 IEEE.

A good systematic input and output management system is more essential for ship maneuvering simulation to eliminate unnecessary error due to many considered factors such as hull shapes, shallow water, narrow channel, trim in loading and ballast condition, and propulsion system. In this paper, we proposed an Integrated Ship Maneuverability Simulation (SMS) tool to be used in investigating turning circle characteristics of a very large crude oil carrier (VLCC) at 35 degree of rudder angle. The input and output datasets from the surrounding environments of VLCC have been captured using special sensors and converted as input file to the Integrated Ship Maneuverability Simulation tool. The forces and moments acting on the hull which have been induced by propeller and rudder during maneuvering are calculated independently. Then, these forces and moments are integrated to the SMS tool in order to get a total dynamic effect on ship maneuvering performance. The simulation results using SMS tool have been compared with the experimental datasets for validation. From the comparison, the proposed SMS tool has been able to simulate ship maneuvering performance good agreement with the experimental dataset.

BPMN, which is the underlying modeling notation of many BPM endeavours and business information system development projects, is a rich modeling language, which also offers redundant constructs, i.e., different syntax can express the same semantics. We want to investigate which syntactical constructs are preferred by model readers if different ways to model message exchanges are offered by BPMN. In an empirical study we asked 77 participants which BPMN model they prefer for expressing eight situations. We found that send tasks and intermediate message catch events are significantly preferred. Also, event-based gateways are preferred over boundary events for many variants of the Deferred Choice pattern. © 2023 Copyright for this paper by its authors.

Security certification assesses the security posture of a software system to verify its compliance with diverse, pre-specified security controls identified by guidelines from NIST and the US Department of Defense. Service-oriented architectures (SOA) are difficult to certify because they require compliance verification over a mix of local, global, and interaction criteria dictated by the policies of the participating services and SOA governance. Web services further contribute to this difficulty because they lack direct methods to express security controls. Besides being understandable, the method of expression should indicate potential problems complying with chosen services. This paper presents a method for configuring of web service standards to enforce security requirements on service interaction specification documents within a SOA. The outcome serves as a mechanism to direct the population of constraints derived from security controls within standards specification documents, such as WS-Policy. We focus on security controls for auditing and how these can be enforced in an SOA. We introduce a reusable architecture to notate the comparison of security controls across services.
