Proceedings of the Workshop on International Transit Turnkey and Joint Development. Session 5: Environmental and Risk Management Considerations

Transportation research circular, Mar 1, 1998

(2) Unresolved environmental issues, since they result in higher risks which in turn result in higher costs, should be avoided. An effort should be made to understand risk probabilities. A proactive environmental management process should be established early in a turnkey procurement process. (3) In a turnkey procurement process, risks must be clearly explicit. Different methods are available to manage risk. A methodology for managing risk was presented. A flow-chart process was also presented to help in the process of identifying and managing risk. The different types of risks were discussed with suggested strategies to manage them. (4) In an effort to foster and direct community participation in transit projects, the Livable Communities Initiative Program was established by the Federal Transit Administration in 1994. A video was presented showing how communities got involved and challenged projects through legal actions in the Los Angeles area. Public Participation/Community Participation should have an active role in every phase of a transit project. (5) The industry is currently developing insurance policies that would protect design liability. Currently, sureties are applicable only in the construction phase of a project. They are also investigating the possibility of Phase Contracting where the owner accepts the risk in the design phase and sureties cover the construction phase. (6) The contractors' perspective in Risk Allocation is: How well companies identify, manage, and mitigate risk directly impact their bottom line. Risk allocation must be balanced between the public and private sector. Risks must be placed where they can best be managed. (7) Bay Area Rapid Transit's experience with environmental considerations in the extension to the San Francisco International Airport was explained. (8) The consultant's perspective with regards to environmental and risk management is: The role of a consultant is to identify clients that have a sound commitment to complete projects. One must know the playing field, understanding clients, stakeholders, and regulatory framework. One must push the limits by understanding best practices, relating innovation to established objectives, and valuing good design.

MyThOS — Scalable OS Design for Extremely Parallel Applications

2016 Intl IEEE Conferences on Ubiquitous Intelligence & Computing, Advanced and Trusted Computing, Scalable Computing and Communications, Cloud and Big Data Computing, Internet of People, and Smart World Congress (UIC/ATC/ScalCom/CBDCom/IoP/SmartWorld), 2016

Scalable throughput can be attained only by a high degree of parallelism, minimized synchronization. Whilst this is achievable for many applications, the operating system still introduces bottlenecks through non-local sharing, synchronization,, message passing. A particular challenge for highly dynamic applications, for example invasive HPC applications, elastic compute clouds, is the management of short-living application threads, processes. This paper discusses OS architecture choices based on microkernel, multikernel, distributed systems designs, our development experience in the context of the MyThOS project. Initial experiments show a much faster thread creation, activation compared to monolithic systems like Linux while providing a more flexible protection, threading model that is better suited for dynamic scenarios. However, despite significant progress in the overall domain of operating systems, the design space for scalable many-core operating systems is yet to be fully explored.

How Cloud Computing, IoT and Multicore Systems Affect Software Engineering Principles

2018 32nd International Conference on Advanced Information Networking and Applications Workshops (WAINA), 2018

The paper presents a concept arising from the EC Cloud Computing expert group between 2012 and 2016 as a means to move away from the hazards of traditional, Turing based computing concepts to an abstract and more natural way of programming. The concept builds up on three major building blocks, namely "Information", "Intention" and "Incentive" to define the behaviour of an application in a fashion that can abstract away from the actual way of executing an algorithm, thus allowing for a larger degree of adaptation, distribution and scale.

Therefore, not all the knowledge can be explicitly formalised. Knowledge and content are multi-and inter-disciplinary long-term targets and values. In practice, powerful and secure information technology can support knowledge-based works and values." "Computing means methodologies, technological means, and devices applicable for universal automatic manipulation and processing of data and information. Computing is a practical tool and has well defined purposes and goals."
