The international Workshop for Autonomous System Safety (IWASS) is a joint effort by the B. John Garrick Institute for the Risk Sciences at the University of California Los Angeles (UCLA-GIRS) and the Norwegian University of Science and Technology (NTNU). IWASS is an invitation-only event designed to be a platform for cross-industrial and interdisciplinary effort and knowledge exchange on autonomous systems. Safety, Reliability, and Security (SRS). The workshop gathers experts from academia, regulatory agencies, and industry to discuss challenges and potential solutions for SRS of autonomous systems.from different perspectives. It complements existing events organized around specific types of autonomous systems.(e.g., cars, ships, aviation) or particular safety or security-related aspects of such systems.(e.g., cyber risk, software reliability, etc.). IWASS distinguishes itself from these events by addressing these topics together and proposing solutions for SRS challenges common to different types of autonomous systems. IWASS 2022 was held on August 28th in Dublin, Ireland, and gathered 30 participants from 20 organizations from around the globe. In addition, a panel session at the European Safety and Reliability conference (ESREL 2023) discussed the workshop's main conclusions and additional points with a larger audience. This report summarizes IWASS 2022 discussions. It provides an overview of the main points raised by a community of experts on the current status of autonomous systems.SRS.

Network operators gradually open their interfaces to formerly hidden services. This fosters the development of a new class of mobile applications that take into account user's location and presence information. However, this development also raises problems especially the lack of protection of privacy in location-based services. This paper proposes a service architecture that is aimed at overcoming some of the shortages of currently existing context-aware applications that make use of network providers services as well as existing mobile payment systems. We therefore introduce the combination of tickets together with a novel privacy enhancing mechanism that is based on the notion of pseudonyms. Compared to other privacy enhancing solutions our pseudonym mechanism can also be implemented on mobile devices that have some restrictions regarding resources like memory or processing power. Due to their flexibility tickets can be used for many different kinds of applications. One important aspect in this respect is the highly postulated pay-as-you-go model. We give an example of a transport ticket application and explain the message interaction patterns for the basic functionalities of the systems. regarding aspects like data and privacy protection. This example further shows how 3rd party application providers can build meaningful mobile applications that are accepted by users

Mobile devices are opening unprecedented opportunities to conduct various social science studies in unobtrusive, large-scale, and longitudinal fashions. Rich dataset captured by smartphones such as communication records, application use patterns and physical sensory readings, serve as basis to understand behavior of human being in depth. Also, crowdsourcing platforms and open-data policy of organizations are enabling scalable data collection and access to such data. Moreover, mobile devices can be used as gateways for real-time intervention and feedback. Such powerful capabilities can enable larger-scale and timely social studies in a cost-effective way beyond traditional study methods such as self-reports, interviews, surveys, and observations under laboratory settings, etc. Many exploratory works have proven that mobile phones are a promising computational platform upon which we plan, develop, and conduct various experimental studies related to social science disciplines.

作者： Paulos Gabriel Zhang Tongkun Zhang Yuqiu Zhu Gerry Karimov Jeyhun Jacobsen Hans Arno University of Toronto Toronto ON Canada

We propose OPTICS, a middleware that optimizes data transfer between the compute layer and the shared object storage in today’s cloud data processing systems. OPTICS implements four data in-teraction patterns to serve a wide spectrum of application needs. Our solution enables synchronous and asynchronous data access from multiple clients and supports transfer of both object stor-age data and object references. As a result, OPTICS significantly reduces network overhead of large object movements. Operating as a client daemon in each compute node, OPTICS can be seam-lessly integrated into any shared-storage cloud architecture with an S3-compatible object storage backend.

Dynamic data integration using Web services

Dynamic data integration using Web services

IEEE international conference on Web Services (ICWS)

We address the problem of large-scale data integration, where the data sources are unknown at design time, are from autonomous organisations, and may evolve. Experiments are described involving a demonstrator system in the field of health services data integration within the UK. Current Web services technology has been used extensively and largely successfully in these distributed prototype systems. The work shows that Web services provide a good infrastructure layer, but integration demands a higher level "broker" architectural layer; the paper identifies eight specific requirements for such an architecture that have emerged from the experiments, derived from an analysis of shortcomings which are collectively due to the static nature of the initial prototype. The way in which these are being met in the current version in order to achieve a more dynamic integration is described.

The aim of this study is to design English intelligent translation system based on 3D visualisation technology. B/S architecture is adopted, with the core functions on the server side and users accessing them through web browsers. Intuitive interactive experience is provided through 3D visualisation technology, and the system hierarchy and modular design improve maintainability. Advanced 3D rendering technology is used to display multi-dimensional data, and users perceive the translation process in the virtual environment. Experiments demonstrate that the system makes significant progress in improving user interaction experience and understanding of the translation process. This research provides practical ideas for the innovation of intelligent translation systems.

作者： Daniel L. Larner Allen-Bradley Co.

The design and implementation of a distributed, Operating System based, Blackboard Architecture for Real-Time control (DOSBART) is described. DOSBART demonstrates the outstanding applicability of AI languages and blackboard techniques to the construction of versatile distributed real-time control frameworks. It provides a means to remotely and transparently execute operations on non-local objects, furnishing the ability to share data and blackboard structures transparently across a network of heterogeneous computers. It allows the simultaneous execution of all blackboard activities by utilizing the underlying operating system's multi-process functionality rather than its own scheduling mechanism. Architectural features are incorporated to deal with distributed real-time control issues such as interrupts, data dependencies, resource contention, activity control and I/O. Computation may occur in both process based and message based perspectives, and may be driven by a first order theorem prover that dynamically infers triggering events, by changes in demoned datums or by arbitrary predicates. The representational capabilities of the Common Lisp Object System (CLOS) were exploited to provide a rich set of base classes from which specific applications can be tailored. Lisp macro facilities support for multiple platforms.
