Impacts of emissions changes from four potential U.S. CO2 emission reduction policies on 2050 air quality are analyzed using the community multiscale air quality model (CMAQ). Future meteorology was downscaled from the Goddard Institute for Space Studies (GISS) ModelE General Circulation Model (GCM) to the regional scale using the Weather Research Forecasting (WRF) model. We use emissions growt...

As environmental standards become more stringent (e.g. European Directive 2008/50/EC), more reliable and sophisticated modeling tools are needed to simulate measures and plans that may effectively tackle air quality exceedances, common in large cities across Europe, particularly for NO2. Modeling air quality in urban areas is rather complex since observed concentration values are a consequence ...

Targeting occupational health and safety interventions to different groups of employees and sectors is important. The aim of this study was to explore the environment-intervention fit of a Danish psychosocial work environment intervention program for the residential and home care sector. Focus group interviews with employees and interviews with mangers were conducted at 12 selected workplaces a...

The paper will address an opportunity for mixed-reality learning in Second Life by discussing the training needs and restrictions for humanitarian and development workers as met by the Open University course TUXR873: Working with conflict: tools, skills and dialogue. The paper will map these needs to the affordances of Second Life, in a context of realistic, practical and sustainable course dev...

The main goal towards which nearly all research activities in the field of digital wireless communications are oriented is the development of a global wireless access network, capable of offering real-time bandwidth-demanding multimedia applications and enabling for anytime/anywhere access. This paper proposes a wireless access network which is a result of the convergence of telecommunications ...

Smart grids have become a topic of intensive research, development, and deployment across the world over the last few years. The engagement of consumer sectors—residential, commercial, and industrial—is widely acknowledged as a key requirement for the projected benefits of smart grids to be realized. Although the industrial sector has traditionally been involved in managing power use with what ...

A macrolevel approach for integrating regional economic models with urban metabolism models is developed. Challenges with consistency and aggregation persist in the integration of urban models between socioeconomic and environmental systems, and between the micro and macro scale. Using an econometric model as a foundation offers a flexible structure, with low data requirements, that might poten...

Residential and commercial buildings constitute one of the largest energy consumption sectors in industrialized countries. This paper introduces a flexible commissioning system for maximizing energy usage efficiency in large and complex buildings. The system exploits (i) a data management scheme that uses distributed wireless sensors networks for environmental monitoring, (ii) a data analysis f...

In this World of Digital era the demand of mobile Internet and wireless multimedia applications are growing faster than ever. To satisfy the user requirements and to overcome the limitations of existing wireless technologies, have led the researchers to come up with more advanced and efficient technology. Orthogonal Frequency Division Multiplexing (OFDM) based WiMAX (Worldwide Interoperability ...

The advent of power quality sensitive equipment has made the provision of good power quality a real challenge across the globe. With the increasing usage of sophisticated sensitive electronic equipment in industrial, residential and commercial sectors, it is important to protect them from any power quality disturbance in order to avoid equipment damage and malfunction leading to financial loss ...
