the distinguishing characteristic in the third millennium is planning based on principles of sustainable development in line with nature and all activities related to urban issues. ecological concepts and consequently ecological park refers to a comprehensive and integrated set of measures which create coordination, balance between the constituent elements of the park in order to establish sust...

Environmental Impact Assessment (EIA) has played an important role in environmental protection, especially in developing countries. It is an aid to decision-making and to the minimization or elimination of environmental impacts at an early planning stage. For geothermal energy, which currently plays an important part as a clean energy supply, a well-prepared Environmental Impact Assessment (EIA...

cities are a focal point of energy consumption. accessibility to public services has a significant impact on the balance of public and private energy uses, which are two sectors that are directly affected by urban planning (the third is industrial). this paper establishes the relative magnitudes of service accessibility enhancement on urban energy efficiency in comparison to other factors, and ...

There has recently been an increased emphasis on reducing energy consumption in manufacturing, driven by the fluctuations in energy costs and the growing importance given to environmental impact of manufactured goods. Lots of attention has been given to the reduction of machine tools energy consumption, as they require large amounts of energy to perform manufacturing tasks. One area that has re...

introduction environment is a pervasive platform for all the living creatures, which is exposed to multiple challenges, especially with the increasing rate of urbanization; levels and dimensions of these threats have increased. scientific activities in a publishing form such as reports and articles is an accepted procedure between various scientific fields. documents, reports and articles are s...

The remarkable development of sciences and technologies in the world of]o today has apparently brought mankind comfort and well-being, but it has also created new problems for humans including environmental pollution, widespread changes in world weather conditions, etc. Fossil fuels cause numerous environmental pollutions. In other words, on the one hand poisonous gases enter the environment fo...

The great attention toward environmental issues and especially on energy utilization, leads the European Union to implement the 2009/28/EC Directive, fixing three main goals to be achieved for 2020 by the EU member states: 20% reduction of the greenhouse gases emission, 20% increase of using renewable energy and 20% improving of energy efficiency. To achieve these objectives, new environmental ...

This paper introduces an energy management system, FeTOP, which provides an optimal operational planning and control scheme of energy plants. It consists of three functions: an energy forecasting function, an optimal operational planning function of the facilities, and a simulation function of the energy plant. In order to generate optimal operational planning for energy plants, startup/shutdow...

The state of California is expected to have significant population growth in the next half-century resulting in additional passenger transportation demand. Planning for a high-speed rail system connecting San Diego, Los Angeles, San Francisco, and Sacramento as well as many population centers between is now underway. The considerable investment in California high-speed rail has been debated for...

We discuss the energy generation expansion planning with environmental constraints, formulated as a nonsmooth convex constrained optimization problem. To solve such problems, methods suitable for constrained nonsmooth optimization need to be employed. We describe a recently developed approach, which applies the usual unconstrained bundle techniques to a dynamically changing “improvement functio...
