abstract urban management forms (model) are a key and important factor on characteristics of urban governance. study of literature and other country’s experience suggest application of various form of urban management and government that each have own specification, legal and administrative characteristics. in iran, in spite of 100 years record in establishing municipalities, there is not any l...

Hybrid electric vehicles employ a hydraulic braking system and a regenerative braking system together to provide enhanced braking performance and energy regeneration. In this paper an integrated braking system is proposed for an electric hybrid vehicle that include a hydraulic braking system and a regenerative braking system which is functionally connected to an electric traction motor. In the ...

urban management in any context has a different economic, social and political structure, which is in harmony with the existing models of organization. in spite of these differences, in order to reach a sustainable urban development, several different conferences should be referred to. in the “brundtland commission 1987” about urban sustainable development these definitions have been given: “pr...

Urban drainage networks (UDN) carry urban wastewater to wastewater treatment plants (WWTP) in order to regenerate it before releasing it to the environment. Combined UDN (CUDN) carry both rain and wastewater together, which can overload the UDN and produce combined sewer overflows (CSO) that pollute the environment. Management of CUDN is receiving increasing attention from both researchers and ...

The ADRICOSM project was launched in October 2001, and ended in March 2005, with the main objective of demonstrating the feasibility of a near real time operational marine monitoring and forecasting system at the shelf and coastal scales, with connections to river basin runoff and coastal town sewer systems. The basic system consisted of an efficient network for the collection of marine data su...

The integration of risk reduction and climate change adaptation has become an urgent task in addressing increasing urban risk more effectively and efficiently. This paper analyses the extent to which climate change adaptation is integrated into the policies and regulatory frameworks that guide urban risk reduction in Nicaragua, and discusses related progress. The results reveal significant prog...

The IEEE/802.16/WiMAX new technology provides wireless wideband access both in rural and urban areas. While the 802.16/WiMAX architectures are already defined in standards and many studies exist, research is still needed, on integration of this access in end-to-end architectures. This paper proposes a flexible architecture for management and control of the IEEE 802.16/WiMAX, used for access to ...

the main purpose of this paper is to study urban management performance in public green spaces (parks) based on economical indexes, social indexes and environmental indexes. for this purposes, we use topsis method that is one of the methods of multiple criteria decision making. the data was obtained through interview and also a questionnaire which was distributed among about 1000 families of ma...

Being as a relatively new approach of signalling, moving-block scheme significantly increases line capacity, especially on congested railways. This paper describes a simulation system for multi-train operation under moving-block signalling scheme. The simulator can be used to calculate minimum headways and safety characteristics under pre-set timetables or headways and different geographic an Q...
