Shipping Emissions and Air Pollution: Latest Methodological Developments and Applications

Latest developments and applications of double-hybrid density functionals

Here we give an overview of the extensions of our previous work. We discuss the analytical gradient for structure optimisations [3], the combination with an empirical dispersion correction (DFT-D) [4], and the computation of excitation energies in a time-dependent framework [5]. We present results for several benchmark sets and for some challenging applications. In all cases very accurate resul...

Medical Waste Incinerator Emissions and Air Pollution Control

Measurements and Modeling of Flue Height Influence on Air Pollution Emissions and Thermal Efficiency of Natural Draught Gas Fired Boilers

This paper presents and analyses results from experimental and CFD work undertaken on a 24 kW domestic natural-draught gas fired boiler. The effect of chimney height on boiler flue gases is being considered to address the need for increasing concern over environmental safety as well as saving of energy. A multi-component analysis computer (DELTA 2000 CD) is used to analyze the flue gases. 3D nu...

GHG emissions from international shipping and aviation

International shipping accounts for about 2 percent of annual global CO2 emissions. Aviation annually contributes to approximately 3.5 percent of the total human climate change effects, taking into account that several emissions from planes contribute. The emissions occur outside national control, and need broad international cooperation to be curbed. Voluntary agreements and technical standard...

The Latest Web Developments

This paper outlines some of the latest World Wide Web developments, in particular standards which are emerging from W3C, the World Wide Web Consortium. The paper gives an overview of the architectural components of the Web, summarise their deficiencies and describe how these deficiencies are being addressed. The paper should be of interest to people involved in developing applications and servi...
