Assessment of Environmental Impacts Related to Shale Gas Extraction in the Polish Contex

In the last decade, the exponential development of shale gas activities in United States resulted in a real revolution both in terms of gas prices and energy security. However, next to these positive effects, many risks and impacts for the environment and ...

Catalysts for High Temperature Gas Cleaning in the Production of Synthetic Natural Gas from Biomass

Bio synthetic natural gas (Bio-SNG) is being proposed as an alternative to the natural gas of fossil origin (NG) [1]. Bio-SNG consists mainly of CH4 (at least 95%mol), has a high heating value (e.g. 10 kWh/m3N), and respects the quality standards of the NG ...

Thermo-chemical H2 production: Thermo-economic modeling and process integration

François Maréchal, Laurence Tock

Within the global challenge of climate change and energy security, hydrogen is considered as a promising decarbonized energy vector to be used in electricity production and transportation. In this paper, the thermo-chemical production of hydrogen by natura ...

A Randomized Countermeasure Against Parasitic Adversaries in Wireless Sensor Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Jun Luo

Due to their limited capabilities, wireless sensor nodes are subject to physical attacks that are hard to defend against. In this paper, we first identify a typical attacker, called parasitic adversary, who seeks to exploit sensor networks by obtaining mea ...

Portable LTCC gas viscometer for determining Wobbe number

Peter Ryser, Thomas Maeder, Conor Joseph Slater

This work presents the continued development of an autonomous portable system for measuring the Wobbe number (calorific content) of gases for the purpose of determining the quality of natural gas. Past research has shown the Wobbe number can be determined ...

How much room is left for European gas incumbents?

Bastian Wolfgang Schwark

In the context of the liberalization of the European natural gas market former monopolists face a challenge to react to market opening by realigning their strategies. Three major groups of companies can be identified that are capable to influence the Europ ...

Important New Nodes; Gas Hubs and their Impact on Competition

Bastian Wolfgang Schwark

Although the gas market in the European Union was opened up with two major directives in 1998 and 2003, competition in Europe is still developing slowly. One major cause is the insufficient availability of gas that is not contracted by long-term contracts ...

Mobility Improves Coverage of Sensor Networks

Olivier Dousse

Previous work on the coverage of mobile sensor networks focuses on algorithms to reposition sensors in order to achieve a static configuration with an enlarged covered area. In this paper, we study the dynamic aspects of the coverage of a mobile sensor net ...

Semi-continuous PM2.5 inorganic composition measurements during the Pittsburgh air quality study

Satoshi Takahama

A method for semi-continuous (10 min time resolution) PM2.5 nitrate and sulfate measurements, based on the humidified impaction with flash volatilization design of Stolzenburg and Hering (Environ. Sci. Technol. 34 (2000) 907), was evaluated during the Pitt ...

Development and application of UV-visible and mid-IR differential absorption spectroscopy techniques for pollutant trace gas monitoring

Rodrigo Jimenez Pizarro

Spatial representativeness is an important quality criterion in trace gas monitoring, especially if measurements are intended for regulatory and model validation purposes. Open-path absorption spectroscopy techniques meet the representativeness requirement ...
