EU — Resilience of Natural Gas Networks during Conflicts, Crises and Disruptions

April 24, 2014 Comments off

Resilience of Natural Gas Networks during Conflicts, Crises and Disruptions
Source: PLoS ONE

Human conflict, geopolitical crises, terrorist attacks, and natural disasters can turn large parts of energy distribution networks offline. Europe’s current gas supply network is largely dependent on deliveries from Russia and North Africa, creating vulnerabilities to social and political instabilities. During crises, less delivery may mean greater congestion, as the pipeline network is used in ways it has not been designed for. Given the importance of the security of natural gas supply, we develop a model to handle network congestion on various geographical scales. We offer a resilient response strategy to energy shortages and quantify its effectiveness for a variety of relevant scenarios. In essence, Europe’s gas supply can be made robust even to major supply disruptions, if a fair distribution strategy is applied.

Next-generation IT infrastructure

Next-generation IT infrastructure
Source: McKinsey & Company

The pressure on IT infrastructure leaders is unrelenting. They must deliver higher service levels and new IT-enabled capabilities, help accelerate application delivery, and do so while managing costs. As standard IT improvements near a breaking point, it’s no wonder that many IT infrastructure leaders have started to look for more transformative options, including next-generation IT infrastructure (NGI)—a highly automated platform for the delivery of IT infrastructure services built on top of new and open technologies such as cloud computing. NGI promises leaner organizations that rely more on cloud-provider-level hardware and software efficiencies. In addition, NGI facilitates better support of new business needs opened up by big data, digital customer outreach, and mobile applications.

To understand how senior executives view NGI, we canvassed opinions from invitees to our semiannual Chief Infrastructure Technology Executive Roundtable. The results were revealing: executives expressed strong interest in all key NGI technologies, from open-source infrastructure-management environments to software-defined networking, software-as-a-service offerings, cloud orchestration and management, and application-configuration management. Yet most have not yet fully taken advantage of the promise of NGI, largely because of the up-front investment required. The immaturity and complexity of the technology is also slowing adoption, as is concern about the security of the public cloud, particularly with respect to companies’ loss of control in the event of private litigation or inquiries from governmental agencies.

Resilient Cities Research Report

Resilient Cities Research Report
Source: Grosvenor

The ability of cities to thrive as centres of human habitation, production and cultural development, despite the challenges posed by climate change, population growth and globalisation, is determined by their resilience. From a real estate investor’s perspective, resilience allows cities to preserve capital values and generate sustainable rental income in the long term. In human terms, cities are resilient if they absorb shocks, like Hurricane Sandy, maintain their output of goods and services and continue to provide their inhabitants with a good quality of life according to the standards of the time.

Resilience – the ability of a city to avoid or bounce back from an adverse event – comes from the interplay of vulnerability and adaptive capacity.

Vulnerability is a city’s exposure to shocks in terms of both magnitude and frequency. Shocks may be due to changes in the climate, environmental degradation, shortage of resources, failed infrastructure or community strife due to inequality. That most cities have survived for the last several centuries or, in some cases, millennia, indicates a long period of stability in the pattern of urban growth. Recent population growth and industrialisation, despite many benefits, are destabilising planetary systems and making previously safe places more vulnerable than they ever were before.

Yet cities, like societies, are adaptable. Just like societies, they vary enormously in their adaptive capacity due to governance, institutions, technology, wealth and the propensity to plan.

So resilience increases when cities have more adaptive capacity and decreases when they are more vulnerable. Exponential population and economic growth is placing so much pressure on resources that resilience, which has for so long been a free gift of history, urgently needs to be rethought.

By quantifying the resilience of 50 of the world’s most important cities we, at Grosvenor, hope to contribute to this vital debate.

Optimal Schedules of Light Exposure for Rapidly Correcting Circadian Misalignment

Optimal Schedules of Light Exposure for Rapidly Correcting Circadian Misalignment
Source: PLoS Computational Biology

Jet lag arises from a misalignment of circadian biological timing with the timing of human activity, and is caused by rapid transmeridian travel. Jet lag’s symptoms, such as depressed cognitive alertness, also arise from work and social schedules misaligned with the timing of the circadian clock. Using experimentally validated mathematical models, we develop a new methodology to find mathematically optimal schedules of light exposure and avoidance for rapidly re-entraining the human circadian system. In simulations, our schedules are found to significantly outperform other recently proposed schedules. Moreover, our schedules appear to be significantly more robust to both noise in light and to inter-individual variations in endogenous circadian period than other proposed schedules. By comparing the optimal schedules for thousands of different situations, and by using general mathematical arguments, we are also able to translate our findings into general principles of optimal circadian re-entrainment. These principles include: 1) a class of schedules where circadian amplitude is only slightly perturbed, optimal for dim light and for small shifts 2) another class of schedules where shifting occurs along the shortest path in phase-space, optimal for bright light and for large shifts 3) the determination that short light pulses are less effective than sustained light if the goal is to re-entrain quickly, and 4) the determination that length of daytime should be significantly shorter when delaying the clock than when advancing it.

Department of Defense (DOD) development work on high-energy military lasers, which has been underway for decades, has reached the point where lasers capable of countering certain surface and air targets at ranges of about a mile could be made ready for installation on Navy surface ships over the next few years. More powerful shipboard lasers, which could become ready for installation in subsequent years, could provide Navy surface ships with an ability to counter a wider range of surface and air targets at ranges of up to about 10 miles.

Quality of Infrastructure is a Top Deal Maker or Breaker for Real Estate Investment and Development Decisions
Source: Urban Land Institute

The quality of infrastructure systems – including transportation, utilities, and telecommunications – is a top factor influencing real estate investment and development decisions in cities around the world, sharing a high ranking with consumer demand in terms of importance, according to a survey of public- and private-sector leaders conducted by the Urban Land Institute and EY. The findings are included in the Infrastructure 2014: Shaping the Competitive City report, released this week at ULI’s 2014 Spring Meeting in Vancouver, British Columbia.

The survey, conducted in January 2014, reflects the opinions of 241 public sector officials and 202 senior-level real estate executives (developers, investors, lenders and advisors) based in large and mid-sized cities across the globe, with concentrations in the United States, Europe and Asia Pacific.

Among the combined group of public and private sector participants, 88 percent rated infrastructure quality as the top influencer of real estate investment and development. Demographic forces, including consumer demand and workforce skills, ranked as other top considerations determining real estate investment locations. Infrastructure quality was rated as the highest influencer by public leaders (91 percent) and second to highest by private leaders (86 percent). Consumer demand was viewed as the top factor by the private sector (90 percent).

Strong telecommunications systems (including high-speed internet capability) led the list of infrastructure categories that drive real estate investment, along with good roads, bridges, and reliable and affordable energy.
