California Water Myths

Presents eight common myths about water supply, ecosystems, and the legal and political aspects of governing California's water system and explains how each myth drives the debate, the reality, and alternatives for better informed policy discussions

Traffic engineering in ambient networks: challenges and approaches

The focus of this paper is on traffic engineering in ambient networks. We describe and categorize different alternatives for making the routing more adaptive to the current traffic situation and discuss the challenges that ambient networks pose on traffic engineering methods. One of the main objectives of traffic engineering is to avoid congestion by controlling and optimising the routing function, or in short, to put the traffic where the capacity is. The main challenge for traffic engineering in ambient networks is to cope with the dynamics of both topology and traffic demands. Mechanisms are needed that can handle traffic load dynamics in scenarios with sudden changes in traffic demand and dynamically distribute traffic to benefit from available resources. Trade-offs between optimality, stability and signaling overhead that are important for traffic engineering methods in the fixed Internet becomes even more critical in a dynamic ambient environment

Impact Investing: a primer for family offices

The goal of this report is to help family offices ask the right questions as they contemplate their path into impact investing. It is important to recognize that impact investing may not suit all investors. There will be family offices which conclude impact investing is not appropriate at this stage for them. While we are passionate about the potential of impact investing, we acknowledge the best future for the sector is where each investor can make informed choices about their own best interest. Each investor and investment institution needs to evaluate if impact investing fits with its needs, interests and unique context. It is with that in mind that we offer this report as a resource and tool that family offices can use to begin the conversations internally, to craft and design their own engagement strategy on impact investing with family members, advisers and potential investees, as well as to ensure that not only is their wealth growing in value, but also that their wealth can reflect their values

RELEASE: A High-level Paradigm for Reliable Large-scale Server Software

Erlang is a functional language with a much-emulated model for building reliable distributed systems. This paper outlines the RELEASE project, and describes the progress in the rst six months. The project aim is to scale the Erlang's radical concurrency-oriented programming paradigm to build reliable general-purpose software, such as server-based systems, on massively parallel machines. Currently Erlang has inherently scalable computation and reliability models, but in practice scalability is constrained by aspects of the language and virtual machine. We are working at three levels to address these challenges: evolving the Erlang virtual machine so that it can work effectively on large scale multicore systems; evolving the language to Scalable Distributed (SD) Erlang; developing a scalable Erlang infrastructure to integrate multiple, heterogeneous clusters. We are also developing state of the art tools that allow programmers to understand the behaviour of massively parallel SD Erlang programs. We will demonstrate the e ectiveness of the RELEASE approach using demonstrators and two large case studies on a Blue Gene
